+The General Public License (GPL)
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
+Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
+verbatim copies of this license document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to most of
+the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you wish), that
+you receive source code or can get it if you want it, that you can change the
+software or use pieces of it in new free programs; and that you know you can do
+these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for a
+fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show
+them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2) offer
+you this license which gives you legal permission to copy, distribute and/or
+modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced by
+others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish
+to avoid the danger that redistributors of a free program will individually obtain
+patent licenses, in effect making the program proprietary. To prevent this, we
+have made it clear that any patent must be licensed for everyone's free use or
+not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+GNU GENERAL PUBLIC LICENSE
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
+MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms of
+this General Public License. The "Program", below, refers to any such program
+or work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or translated
+into another language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered by
+this License; they are outside its scope. The act of running the Program is not
+restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made by
+running the Program). Whether that is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code as
+you receive it, in any medium, provided that you conspicuously and appropriately
+publish on each copy an appropriate copyright notice and disclaimer of warranty;
+keep intact all the notices that refer to this License and to the absence of any
+warranty; and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may at
+your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it, thus
+forming a work based on the Program, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that you also
+meet all of these conditions:
+
+a) You must cause the modified files to carry prominent notices stating that you
+changed the files and the date of any change.
+
+b) You must cause any work that you distribute or publish, that in whole or in
+part contains or is derived from the Program or any part thereof, to be licensed
+as a whole at no charge to all third parties under the terms of this License.
+
+c) If the modified program normally reads commands interactively when run, you
+must cause it, when started running for such interactive use in the most ordinary
+way, to print or display an announcement including an appropriate copyright
+notice and a notice that there is no warranty (or else, saying that you provide a
+warranty) and that users may redistribute the program under these conditions,
+and telling the user how to view a copy of this License. (Exception: if the
+Program itself is interactive but does not normally print such an announcement,
+your work based on the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as
+separate works. But when you distribute the same sections as part of a whole
+which is a work based on the Program, the distribution of the whole must be on
+the terms of this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your rights to
+work written entirely by you; rather, the intent is to exercise the right to control
+the distribution of derivative or collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program with the
+Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and 2
+above provided that you also do one of the following:
+
+a) Accompany it with the complete corresponding machine-readable source
+code, which must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange; or,
+
+b) Accompany it with a written offer, valid for at least three years, to give any
+third party, for a charge no more than your cost of physically performing source
+distribution, a complete machine-readable copy of the corresponding source
+code, to be distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+c) Accompany it with the information you received as to the offer to distribute
+corresponding source code. (This alternative is allowed only for noncommercial
+distribution and only if you received the program in object code or executable
+form with such an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all the
+source code for all modules it contains, plus any associated interface definition
+files, plus the scripts used to control compilation and installation of the
+executable. However, as a special exception, the source code distributed need
+not include anything that is normally distributed (in either source or binary form)
+with the major components (compiler, kernel, and so on) of the operating system
+on which the executable runs, unless that component itself accompanies the
+executable.
+
+If distribution of executable or object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the source
+code from the same place counts as distribution of the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses terminated so long
+as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed it.
+However, nothing else grants you permission to modify or distribute the Program
+or its derivative works. These actions are prohibited by law if you do not accept
+this License. Therefore, by modifying or distributing the Program (or any work
+based on the Program), you indicate your acceptance of this License to do so,
+and all its terms and conditions for copying, distributing or modifying the
+Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program),
+the recipient automatically receives a license from the original licensor to copy,
+distribute or modify the Program subject to these terms and conditions. You
+may not impose any further restrictions on the recipients' exercise of the rights
+granted herein. You are not responsible for enforcing compliance by third parties
+to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent infringement
+or for any other reason (not limited to patent issues), conditions are imposed on
+you (whether by court order, agreement or otherwise) that contradict the
+conditions of this License, they do not excuse you from the conditions of this
+License. If you cannot distribute so as to satisfy simultaneously your obligations
+under this License and any other pertinent obligations, then as a consequence
+you may not distribute the Program at all. For example, if a patent license would
+not permit royalty-free redistribution of the Program by all those who receive
+copies directly or indirectly through you, then the only way you could satisfy
+both it and this License would be to refrain entirely from distribution of the
+Program.
+
+If any portion of this section is held invalid or unenforceable under any particular
+circumstance, the balance of the section is intended to apply and the section as
+a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or other
+property right claims or to contest validity of any such claims; this section has
+the sole purpose of protecting the integrity of the free software distribution
+system, which is implemented by public license practices. Many people have
+made generous contributions to the wide range of software distributed through
+that system in reliance on consistent application of that system; it is up to the
+author/donor to decide if he or she is willing to distribute software through any
+other system and a licensee cannot impose that choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain countries
+either by patents or by copyrighted interfaces, the original copyright holder who
+places the Program under this License may add an explicit geographical
+distribution limitation excluding those countries, so that distribution is permitted
+only in or among countries not thus excluded. In such case, this License
+incorporates the limitation as if written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of the
+General Public License from time to time. Such new versions will be similar in
+spirit to the present version, but may differ in detail to address new problems or
+concerns.
+
+Each version is given a distinguishing version number. If the Program specifies a
+version number of this License which applies to it and "any later version", you
+have the option of following the terms and conditions either of that version or of
+any later version published by the Free Software Foundation. If the Program does
+not specify a version number of this License, you may choose any version ever
+published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status of all
+derivatives of our free software and of promoting the sharing and reuse of
+software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
+NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
+"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
+IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
+YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED
+TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY
+WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS
+PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
+OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS

+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+=head1 SYNOPSIS
+
+C<pXtools> is a collection of utilties for tracking image processing
+tasks.  Very little decision making logic is built into these programs.  The
+intent is for higher level programs and scripts to make the real I<decisions>
+and then use C<pXtools> to encode those choices in a persistent manner.
+
+=head1 INSTALL
+
+=head2 Prerequisites
+
+C<pXtools> depends on C<psLib> (built with C<psDB> support), C<psModules>, and
+C<ippdb> and requires a C<C99> capable compiler.
+
+XXX document required library versions
+
+=head2 Build Procedure
+
+C<pXtools> is built with the so-called suite of autotools.   The build
+procedure is pretty typical for software built with these tools.  E.g.
+    
+    ./configure
+    make
+    make install
+
+If you checked out the sources directly from CVS you need to run the
+C<autogen.sh> script.  C<autogen.sh> will run C<configure> for you so that
+changes the build procedure to just:
+
+    sh autogen.sh
+    make
+    make install
+
+=head2 jhbuild Build Procedure
+
+If you are using one of the C<ippdev> modulesets jhbuild can build and install C<pXtools> for you.  E.g.
+
+    jhbuild build pxtools
+    
+=head2 Database Setup
+
+All of the C<pXtools>' persistent storage is ultimately done through C<psLib>'s
+C<psDB> facilties.  In turn, C<psDB> uses C<MySQL> to impliment storage (and
+relational querying).  C<MySQL> requires that each namespace (aka database) is
+configured with basic access controls.  These include usernames, passwords,
+access filtering, and privilege restrictions.  Below is a simple (but somewhat
+dangerous) example of configuring a database named C<ipp>.
+
+    mysql -u root mysql -p
+    (enter your MySQL root password)
+
+    DROP DATABASE IF EXISTS ipp;
+    CREATE DATABASE ipp;
+    GRANT ALL PRIVILEGES ON *.* TO 'ippuser'@'localhost' IDENTIFIED BY 'ipppass';
+    FLUSH PRIVILEGES;
+    quit
+
+After setting up the database you should verify that you can connect to with the username and password you configured
+
+    mysql -u ipp ipp -pipp
+
+Next, C<pXtools> needs to be told where to to find MySQL, the name of the
+database you created, the username, and the password you created.  C<pXtools>
+uses the typical C<psModules> configuration system.  The simplest method is to
+add the follow lines to your $HOME/.ipprc file.
+
+    ### Database configuration
+    DBSERVER        STR     localhost   # Database host name (for psDBInit)
+    DBNAME          STR     ipp
+    DBUSER          STR     ipp         # Database user name (for psDBInit)
+    DBPASSWORD      STR     ipp         # Database password (for psDBInit)
+
+The C<pxTools> utilities require the a schema is pre-loaded into the database.  The C<pxadmin> tool can do this for you.  E.g.
+
+    pxadmin -create
+
+You should always verify that the scheme was actually loaded.  E.g.
+
+    mysql -u ipp ipp -pipp
+    Welcome to the MySQL monitor.  Commands end with ; or \g.
+    Your MySQL connection id is 6 to server version: 4.1.20-log
+
+    Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

+    mysql> show tables;

+
+=head1 USE
+
+The workflow is as follows:
+
+XXX
+
+=head2 Phase 0 tools
+
+The primary C<pXtools> utility for handling Phase 0 is C<p0search>.  This tool
+has two modes C<-pending> and C<-update>. The pending mode lists all
+C<newImfile>s that are part of an exposure that I<has not> yet been classified
+as either science or detrend data.
+
+For example:
+
+    p0search -pending
+
+Would output something like:
+
+    newImfile MULTI #
+
+    newImfile  METADATA
+       exp_id STR  10
+       class STR  OTA
+       class_id STR  0
+       uri STR  file://0
+    END
+
+    newImfile  METADATA
+       exp_id STR  10
+       class STR  OTA
+       class_id STR  1
+       uri STR  file://1
+    END
+
+    newImfile  METADATA
+       exp_id STR  10
+       class STR  OTA
+       class_id STR  2
+       uri STR  file://2
+    END
+
+    newImfile  METADATA
+       exp_id STR  10
+       class STR  OTA
+       class_id STR  3
+       uri STR  file://3
+    END
+
+To declare C<exp_id 10> as science data, you would invoke C<p0search> like this:
+    
+    p0search -update -exp_id 10
+
+Note that by default C<-update> flags the exposure as science data.  To declare it to be detrend data the command would be:
+
+    p0search -update -exp_id 10 -detrend
+
+Also keep in mind that this is a one time declaration.  Once it has been
+declared as either science or detrend data this decision can not be undone
+(without manually editing the database)
+
+=head2 Phase 1 tools
+
+These tools are not yet in use.
+
+=head2 Phase 2 tools
+
+C<p2search> handles all of state for Phase 2.  It has four basic modes:
+
+=over 4
+
+=item * C<-quick>
+
+=item * C<-define>
+
+=item * C<-pending>
+
+    p0search -pending
+
+=item * C<-done>
+
+=head2 Administrative tools
+
+=over 4
+
+=item * C<pxadmin>
+
+This tool can be used to load/unload the database schema.  It has three modes of operation:
+
+=over 4
+
+=item * C<-create>
+
+Loads the database schema.
+
+=item * C<-delete>
+
+Deletes the database schema.
+
+=item * C<-recreate>
+
+Deletes the database schema then reloads it.
+
+=back
+
+=item * C<pxinject>
+
+I<Injects> data directly into the database.  It has one mode parameter for each database table.  Note: support for only a few tables has been impliemented.
+
+=back
+
+=head2 Bypassing 'Summit Copy'
+
+The C<pXtools> suite assumes that exposures and image data are initially
+registered with the C<pz*> set of I<Summit Copy step> tools.  Sometimes this is
+inconvenient as you want to work with local data and bypass this set.  This is
+what the C<pxinject> utility is for.  C<pxinject> directly inserts data into
+the database, side stepping any ordering rules or sanity checking.
+
+The end result of the C<pz*> utilities is that new exposures are registered in the C<newExp> table and raw image data is in the C<newImfile> table.  You can insert this data yourself, preparing the system to run I<phase 0>.
+
+Here is an example of inserting an exposure that has 4 component image files.
+
+    #!//bin/sh
+
+    inject="./pxinject"
+
+    $inject -newExp -exp_id 10 -inst gpc -telescope ps1 -exp_type object -imfiles 4
+
+    `$inject -newImfile -exp_id 10 -class OTA -class_id 0 -uri file://0`
+    `$inject -newImfile -exp_id 10 -class OTA -class_id 1 -uri file://1`
+    `$inject -newImfile -exp_id 10 -class OTA -class_id 2 -uri file://2`
+    `$inject -newImfile -exp_id 10 -class OTA -class_id 3 -uri file://3`

+The summit copy phase (phase Z or pz) consists of three basic steps.
+Discovering what exposures and available, discovering what image files are
+associated with those exposures, and the downloading of image files.  All
+"external" communication with the DataStore is done with three utilities;
+pzgetexp, pzgetimfiles & dsget.  While local state information is accessed and
+updated via the 'pztool' utility.
+
+The basic work follow is:
+
+pzgetexp retrieves a list of all of the exposures (filesets) available from a
+DataStore "product".  If any previously unknown file exposures are found they
+are added to the pzPendingExp tables and the summitExp table.  New entries to
+the summitExp table have a imfile value of NULL as this information can't yet
+be known.  If any exposures are already in the summitExp table the most recent
+exp_id is used to constrain the result set requested from the DataStore.
+
+    ./pzgetexp -uri http://otis/ds/skyprobe/ -inst skyprobe -telescope ps1
+
+The results of pzgetexp and accessible with pztool -pendingexp`.  Which will
+return a list of new exposures from the pzPendingExp table.
+
+    ./pztool -pendingexp
+
+The output of which is used to invoke pzgetimfiles.
+
+pzgetimfiles retrieves a list of all of the imfiles (files) in an exposure
+(fileset) from the DataStore.  It then updates the imfiles count in the
+summitExp table and adds each imfile to the pzPendingImfile table.
+
+./pzgetimfiles -uri http://otis/ds/skyprobe/sep8_twi_05/ -filesetid sep8_twi_05 -inst skyprobe -telescope ps1
+
+pztool -pendingimfile returns the list of imfiles that need to be downloaded.
+
+    ./pztool -pendingimfile
+
+The results of which are used to invoke dsget and pztool -copydone after dsget
+completes it's download.
+
+dsget from the 'DataStore' package takes the follow parameters.
+
+    dsget --uri <uri> --filename <filename> [--bytes <nbytes>] [--md5 <hex>]
+
+Where "filename" may be either just a filename relative to the CWD or a fully
+qualified path.  After dsget has copied the file pztool -copydone needs to be
+invoked
+
+    ./pztool -copydone -exp_id sep8_twi_03 -inst skyprobe -telescope ps1 -class chip -class_id sep8_twi_03.fits -uri file///data/alala/sep8_twi_03.fits

+# this file contains the list of valid photometry codes.  there should
+# be one code for each combination of CCD, filter, and telescope (and
+# possibly additional ones if filter transmission reduces with time).
+# The code on each line is a unique number, while the name is a
+# representative name.  The type defines how the photometry is
+# treated.  There can only be one primary photcode.  There should only
+# be a few secondary photcodes: these are the calibrated values for
+# stars.  The dependent photcodes are those which are equivalent to a
+# primary or secondary photcode, and are equated after photometric
+# solutions.  Reference photcodes are for anything without a dynamic
+# solution: the reference values are provided externally.
+
+# NOTE: the photcodes defined below supplement CFHT Elixir values.
+# Do not use this photcode file with old CFHT DVO databases.

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes a while.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Type `make install' to install the programs and any data files and
+     documentation.
+
+  4. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+   this function creates WCS terms which convert directly from chip to sky.
+   this function requires a linear, unrotated toTPA distortion term
+   toTPA->x,y->coeff[1][0],[0][1] defines the detector scale (microns / pixel)
+   tpSky->Xs,Ys defines the plate scale (radians / micron)
+*/
+
+/* at this point, we have extracted from the header the WCS terms in the form of a polynomial,
+ * wcs->trans, which will convert X,Y in pixels to L,M in degrees.  we also have the following 
+ * elements defined:
+ * type (projection type)
+ * crval1,2 (in RA,DEC degrees)
+ * crpix1,2 
+ * cdelt1,2 (in degrees / pixel)
+ * pixelScale (microns / pixel)
+ * 
+ * now we convert wcs->trans to toFPA, which is different from wcs->trans in 3 important ways:
+ * 1) the output is in microns (not degrees): divide by cdelt1,2
+ * 2) X,Y are applied directly, without an applied Xo,Yo offset
+ * 3) there is an allowed Lo,Mo term ([0][0] coefficients)

+// It is desirable to do this without using psImageOverlay (or similar) if it can be at all avoided (because
+// it's really really slow in that case).  There are therefore two cases:
+//
+// 1. The HDU is at the Chip or FPA level.  This is the fast case, and only works if the HDU is "nice", by
+// which I mean:
+//
+//    - the CELL.TRIMSECs are contiguous on the HDU image
+//    - the CELL.PARITYs are identically +1
+//    - the CELL.XBIN and CELL.YBIN are all identical
+//
+// Then we can just use psImageSubset to get the "mosaicked" chip.
+//
+//
+// 2. The HDU is at the cell level, or the above requirements are not met, in which case we mosaic the cells.
+// This is the slow case.  We need to:
+//
+//    - Throw away the bias regions
+//    - Convert all cells to common parity
+//    - Mosaic the cells into an HDU image using CELL.X0 and CELL.Y0
+//    - Update CELL.TRIMSECs
+//
+// Once the demands of case 1 have been met, or case 2 has been performed, then we can create a cell to hold
+// the mosaic image.

+/// Measure shutter correction:
+///
+/// input  : collection of shutter correction exposures (pre-processed)
+/// output : a shutter correction image
+///
+/// The measurement could be performed on any focal-plane unit at a time. for GPC, the obvious scale is to
+/// measure the effect on the entire focal plane at once, with a single reference point in the field.  this is
+/// a little more complex than just measuring the effect for a single 2D image array.  the reference point and
+/// the detailed analysis points need to be defined for the entire hierarchy rather than just as coordinate
+/// pairs or regions.  a pmFPAview would be a natural element with which to define these points, but at the
+/// moment, the pmFPAview structure defines a band in the CCD, not a coordinate.  An option is to instead
+/// specify the reference locations as a pmFPAview coupled with a psRegion, though we need to be careful not
+/// to over-specify the pixels (ie, conflict between pmFPAview and psRegion).
+///
+/// At each point in an image with exposure time T, we measure f(k;T) = F(k;T) / F(0;T) where k is the
+/// coordinate of the point of interest, 0 is the reference coordinate, and F(k;T) is the measured number of
+/// counts at the point of interest in this image.  given a collection of f(k;T) values, we need to determine
+/// the model f(k;T) = A(k) (T + dTk) / (T + dTo) where dTk is the shutter error at the given position, dTo is
+/// the shutter error at the reference position, and A(k) is the scaling factor for the given position.
+///
+/// The process for generating a shutter correction is as follows:
+/// - for each image
+/// -- measure the reference point counts
+/// - for each analysis region:
+/// -- measure shutter parameters (dTo, dTk, A):
+/// --- for each image:
+/// ---- measure counts at the region
+/// ---- divide by the reference counts
+/// --- linear extrapolation to find f(inf) = A(k)
+/// --- linear extrapolation to find f(0) = A(k) dTk / dTo
+/// --- linear interpolation to find coordinate where f(dTo) = A (1 + dTk/dTo) / 2
+/// --- non-linear fit of T, f(T) to f(k;T) = A(k) (T + dTk) / (T + dTo)
+/// - use the collection of dTo values to choose a best value for dTo (median)
+/// - for each image pixel
+/// -- divide by the reference counts
+/// -- generate the vectors T, f(T)
+/// -- linear fit of T, f(T) to f(k;T) = A(k) (T + dTk) / (T + dTo) using dTo above

+
+/*  A mechanical shutter may not yield uniform exposure times as a function of
+ *  position on the detector.  The typical error consists of a constant
+ *  exposure-time offset relative to the requested value, ie exposure time is
+ *  T_o + dT(x,y).  The exposure error, dT, may be measured with the following
+ *  scheme.  Obtain a set of exposures with different exposures times taken of
+ *  the same flat-field source; the source must be spatially stable between the
+ *  exposures, but need not have a stable amplitude.  For an illuminating flux
+ *  of intensity F(x,y) = F_o f(x,y), the signal recorded by any pixel in the
+ *  detector is given by: S(t,x,y) = F_o(t) f(x,y) (T_o + dT(x,y)) where F_o is
+ *  the F_o(t) is the (variable) overall intensity of the illuminating source
+ *  and f(x,y) is the spatial illumination patter times the flat-field response.
+ *  Choose a reference location in the image (eg, the detector center) and
+ *  divide by the value of that region (ie, mean or median):
+ *
+ *  s(t,x,y) = S(t,x,y) / S(t,0,0)
+ *  s(t,x,y) = F_o(t) f(x,y) (T_o + dT(x,y)) / F_o(t) f(0,0) (T_o + dT(0,0))
+ *  s(t,x,y) = f(x,y) (T_o + dT(x,y)) / f(0,0) (T_o + dT(0,0))
+ *
+ *  we can absorb the term f(0,0) into f(x,y) as we have no motivation for the
+ *  scale of f(x,y).  For any single pixel, over the set of exposures, we thus
+ *  need to solve for dT(x,y), dT(0,0), and f'(x,y) in the equation:
+ *  s(t,x,y) = f'(x,y) (T_o + dT(x,y)) / (T_o + dT(0,0))
+ *
+ *  we avoid directly fitting these values as the process would be a non-linear
+ *  least-squares problem for every pixel in the image, and thus very time
+ *  consuming.  There are linear options which may be used instead.
+ *  First, as T_o goes to a large value, s() approaches the value of f'(x,y).
+ *  Next, as T_o goes to a very small value, s() approaches the value of
+ *  f'(x,y)*dT(x,y)/dT(0,0).  Finally, when s() has the value of
+ *  f'(x,y)*(1 + dT(x,y)/dT(0,0))/2, T_o has the value of dT(0,0).  with data
+ *  points covering a reasonable dynamic range, we can solve for these three
+ *  values by interpolation and/or extrapolation.
+ *
+ *  To take the strategy one step further, we could use the above recipe to
+ *  obtain a guess for the three parameters and then apply non-linear fitting to
+ *  solve more accurately for the parameters.  If we limit this operation to a
+ *  handful of positions in the image (user defined, but the obvious choice would
+ *  be positions near the center, edges, and corners), then we may determine a
+ *  good value for dT(0,0).  Since there is only one dT(0,0) for the image, we
+ *  can apply the resulting measurement to the rest of the pixels in the image.
+ *  If dT(0,0) is not a free parameter, then the fitting process is linear in
+ *  terms of dT(x,y) and f'(x,y)

+/** @mainpage psModules Image Processing Library
+
+
+@section intro Introduction
+This library contains the Pan-STARRS Image Processing Pipeline (IPP) modules (psModules). These modules
+use the functionality of the Pan-STARRS Library (psLib) to perform more complex tasks associated with image
+processing. Modules were constructed to support each of the required processing stages and are listed according
+to the particular processing stage for which they will primarily be used. To preserve namespace, globally-visible
+structures and functions are prefixed with pm, an abbreviation for Pan-STARRS Modules.
+
+The capabilities provided by psModules are grouped into the following areas which are
+also reflected in the file system directory structure:
+ - Configuration
+ - Astrometry, Focal Plane
+ - Photometry
+ - Basic Image Detrending
+ - Object Detection and Classification
+ - Image Combination
+ - Image Subtraction
+
+The installed code for psModules consists of header files and a binary library.
+
+@section extinstall Required external Libraries
+
+Before building psLib from source, several external software libraries must
+be installed. These include:
+ - Pan-STARRS Library (psLib)
+     - Available from the Maui High Performance Computiong Center (MHPCC) at https://mhpcc.pan-starrs.org/code/releases
+     - Compatibility tested with rel5
+     - Note, psLib itself has many external library dependencies.
+ - Doxygen Documentation System
+     - Only needed if code documentation is to be made
+     - Available at http://www.doxygen.org
+     - Compatibility tested with version 1.3.6
+     - The optional companion package, GraphViz (a.k.a., the 'dot' command), is recommended to enable header-file dependency diagrams
+
+We recommend using the particular versions listed as compatibility tested, as
+that is the only versions of the external libraries tested to work well with psLib
+and psModules.  Though it is quite possible that later versions of the libraries
+listed will also work, care must be taken when upgrading these libraries to verify
+that its functionality is compatible with the tested version.
+
+@section install How to Build from Source
+
+Tested versions of psModules are put into a tar file and can be downloaded from:
+
+https://mhpcc.pan-starrs.org/code/releases
+
+If one has a login account on mhpcc.pan-starrs.org, direct CVS access is
+possible.  Example of the commands required for direct CVS retrieval are
+as follows:
+<pre>
+$ cvs -d:ext:USERNAME@mhpcc.pan-starrs.org:/data/panstarrs/cvsroot co -r RELEASEBRANCH psModule
+</pre>
+where:
+  - USERNAME is your login name on the server
+  - RELEASEBRANCH is the desired release branch, e.g. rel7.
+
+
+@section build How to Build and Test the psModules Library.
+
+The psModules library and associated tests are made via the GNU autoconf/automake system.
+
+The source should build using the configure script in the psModules directory.  The
+recommended steps are:
+<pre>
+$ cd psmodules
+$ ./configure
+$ make
+$ make check
+$ make install
+</pre>
+<i>Unless otherwise specified, the library is installed with PREFIX of the current directory.</i>
+
+If the code was retrieved from CVS, you will need to substitute 'autogen.sh' for 'configure' in
+above example.
+
+Other configuration options, such as location of external libraries, are also available.
+To get a list of options, type the following in the top psModules directory.
+<pre>
+$ configure --help
+</pre>
+A likely option needed is '--with-pslib-config', which specifies the location of
+the configuration script for psLib.  By default, configure searches for it using PATH, but that
+is not always sufficient.
+
+@section install How to Install
+
+To install the library using the prefix given in the configure step, execute in
+the top build directory:
+<pre>
+$ make install
+</pre>
+
+
+@section usage Building and Linking your code to the psModules library
+
+To assist the use of the library with your own code, a configuration tool is part
+of the psModules library package.  This tool, psmodules-config, is installed in the BIN
+directory, according to the options given to the configure script.
+
+The required CFLAG options for the compiler stage of code that uses psModules can be
+obtained via 'psmodules-config --cflags'.  This outputs the cc options that supplies
+include path(s) required to find the psModules headers.
+
+The required linking options, can be obtained via 'psmodules-config --libs'.  This
+outputs the ld options that supplies the library paths and files required to
+link to the psModules library.
+
+Note: psmodules-config usage above refers to the install locations of the library.  
+
+@section doc How to Create Code Documentation
+
+Both HTML and man page documentation may be generated from the inline
+documentation embedded in the code using the following commands:
+<pre>
+$ cd psmodules
+$ make docs
+</pre>
+<i>This places documentation in PREFIX/docs.</i>
+
+Also, a prebuilt set of code documentation for both the releases and last
+CVS snapshot can be found at:
+
+https://mhpcc.pan-starrs.org/docs/

+ * this file defines the GAUSS source shape model.  Note that these model functions are loaded
+ * by pmModelGroup.c using 'include', and thus need no 'include' statements of their own.  The
+ * models use a psVector to represent the set of parameters, with the sequence used to specify
+ * the meaning of the parameter.  The meaning of the parameters may thus vary depending on the
+ * specifics of the model.  All models which are used a PSF representations share a few
+ * parameters, for which # define names are listed in pmModel.h:
+
+   pure Gaussian:
+   exp(-z)
+
+ * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+ * PM_PAR_I0 1    - central intensity
+ * PM_PAR_XPOS 2  - X center of object
+ * PM_PAR_YPOS 3  - Y center of object
+ * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) * SigmaX)
+ * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) * SigmaY)
+ * PM_PAR_SXY 6   - X*Y term of elliptical contour

+ * this file defines the PGAUSS source shape model.  Note that these model functions are loaded
+ * by pmModelGroup.c using 'include', and thus need no 'include' statements of their own.  The
+ * models use a psVector to represent the set of parameters, with the sequence used to specify
+ * the meaning of the parameter.  The meaning of the parameters may thus vary depending on the
+ * specifics of the model.  All models which are used a PSF representations share a few
+ * parameters, for which # define names are listed in pmModel.h:
+
+   Gaussian taylor expansion
+   1 / (1 + z + z^2/2 + z^3/6)
+
+ * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+ * PM_PAR_I0 1    - central intensity
+ * PM_PAR_XPOS 2  - X center of object
+ * PM_PAR_YPOS 3  - Y center of object
+ * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) * SigmaX)
+ * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) * SigmaY)
+ * PM_PAR_SXY 6   - X*Y term of elliptical contour

+ * this file defines the QGAUSS source shape model (XXX need a better name!).  Note that these
+ * model functions are loaded by pmModelGroup.c using 'include', and thus need no 'include'
+ * statements of their own.  The models use a psVector to represent the set of parameters, with
+ * the sequence used to specify the meaning of the parameter.  The meaning of the parameters
+ * may thus vary depending on the specifics of the model.  All models which are used a PSF
+ * representations share a few parameters, for which # define names are listed in pmModel.h:
+
+   power-law with fitted linear term
+   1 / (1 + kz + z^2.25)
+
+   * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+   * PM_PAR_I0 1    - central intensity
+   * PM_PAR_XPOS 2  - X center of object
+   * PM_PAR_YPOS 3  - Y center of object
+   * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) / SigmaX)
+   * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) / SigmaY)
+   * PM_PAR_SXY 6   - X*Y term of elliptical contour
+   * PM_PAR_7   7   - amplitude of the linear component (k)

+ * this file defines the RGAUSS source shape model (XXX need a better name!).  Note that these
+ * model functions are loaded by pmModelGroup.c using 'include', and thus need no 'include'
+ * statements of their own.  The models use a psVector to represent the set of parameters, with
+ * the sequence used to specify the meaning of the parameter.  The meaning of the parameters
+ * may thus vary depending on the specifics of the model.  All models which are used a PSF
+ * representations share a few parameters, for which # define names are listed in pmModel.h:
+
+   power-law with fitted slope
+   1 / (1 + z + z^alpha)
+
+ * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+ * PM_PAR_I0 1    - central intensity
+ * PM_PAR_XPOS 2  - X center of object
+ * PM_PAR_YPOS 3  - Y center of object
+ * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) / SigmaX)
+ * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) / SigmaY)
+ * PM_PAR_SXY 6   - X*Y term of elliptical contour

+/******************************************************************************
+ * this file defines the SERSIC source shape model.  Note that these model functions are loaded
+ * by pmModelGroup.c using 'include', and thus need no 'include' statements of their own.  The
+ * models use a psVector to represent the set of parameters, with the sequence used to specify
+ * the meaning of the parameter.  The meaning of the parameters may thus vary depending on the
+ * specifics of the model.  All models which are used a PSF representations share a few
+ * parameters, for which # define names are listed in pmModel.h:
+
+   f = exp(-z^n)
+
+   * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+   * PM_PAR_I0 1    - central intensity
+   * PM_PAR_XPOS 2  - X center of object
+   * PM_PAR_YPOS 3  - Y center of object
+   * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) / SigmaX)
+   * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) / SigmaY)
+   * PM_PAR_SXY 6   - X*Y term of elliptical contour
+   * PM_PAR_7   7   - normalized sersic parameter
+
+   note that a standard sersic model uses exp(-K*(z^(1/n) - 1).  the additional elements (K,
+   the -1 offset) are absorbed in this model by the normalization, the exponenet, and the
+   radial scale.  We fit the elements in this form, then re-normalize them on output.

+ * this file defines the SGAUSS source shape model (XXX need a better name!).  Note that these
+ * model functions are loaded by pmModelGroup.c using 'include', and thus need no 'include'
+ * statements of their own.  The models use a psVector to represent the set of parameters, with
+ * the sequence used to specify the meaning of the parameter.  The meaning of the parameters
+ * may thus vary depending on the specifics of the model.  All models which are used a PSF
+ * representations share a few parameters, for which # define names are listed in pmModel.h:
+
+   power-law with fitted slope and outer tidal radius
+   1 / (1 + z^N + kz^4)
+
+   * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+   * PM_PAR_I0 1    - central intensity
+   * PM_PAR_XPOS 2  - X center of object
+   * PM_PAR_YPOS 3  - Y center of object
+   * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) / SigmaX)
+   * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) / SigmaY)
+   * PM_PAR_SXY 6   - X*Y term of elliptical contour
+   * PM_PAR_7   7   - slope of power-law component (N)
+   * PM_PAR_8   8   - amplitude of the tidal cutoff (k)
+   *****************************************************************************/
+
+/***
+    XXXX the model in this file needs to be tested more carefully.
+    the code for guessing the power-law slope based on the radial profile

+ * this file defines the ZGAUSS source shape model (XXX need a better name!).  Note that these
+ * model functions are loaded by pmModelGroup.c using 'include', and thus need no 'include'
+ * statements of their own.  The models use a psVector to represent the set of parameters, with
+ * the sequence used to specify the meaning of the parameter.  The meaning of the parameters
+ * may thus vary depending on the specifics of the model.  All models which are used a PSF
+ * representations share a few parameters, for which # define names are listed in pmModel.h:
+
+   power-law with fitted slope and tidal cutoff
+   1 / (1 + z^N + (Az)^4)
+
+   * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+   * PM_PAR_I0 1    - central intensity
+   * PM_PAR_XPOS 2  - X center of object
+   * PM_PAR_YPOS 3  - Y center of object
+   * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) / SigmaX)
+   * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) / SigmaY)
+   * PM_PAR_SXY 6   - X*Y term of elliptical contour

+ * The object model function types are desined to allow for the flexible addition of new
+ * object models. Every object model, with parameters represented by pmModel, has an
+ * associated set of functions which provide necessary support operations.  A These
+ * functions allow the programmer to select the approriate function or property for a
+ * specific object model class.
+ *
+ * Every model instance belongs to a class of models, defined by the value of the
+ * pmModelType type entry. Various functions need access to information about each of the
+ * models. Some of this information varies from model to model, and may depend on the
+ * current parameter values or other data quantities. In order to keep the code from
+ * requiring the information about each model to be coded into the low-level fitting
+ * routines, we define a collection of functions which allow us to abstract this type of
+ * model-dependent information. These generic functions take the model type and return the
+ * corresponding function pointer for the specified model. Each model is defined by
+ * creating this collection of specific functions, and placing them in a single file for
+ * each model. We define the following structure to carry the collection of information
+ * about the models.

+/* @file  pmModelGroup.h
+ *
+ * The object model function types are desined to allow for the flexible addition of new object
+ * models. Every object model, with parameters represented by pmModel, has an associated set of
+ * functions which provide necessary support operations. A set of abstract functions allow the
+ * programmer to select the approriate function or property for a specific named object model.
+ *
+ * Every model instance belongs to a class of models, defined by the value of
+ * the pmModelType type entry. Various functions need access to information about
+ * each of the models. Some of this information varies from model to model, and
+ * may depend on the current parameter values or other data quantities. In order
+ * to keep the code from requiring the information about each model to be coded
+ * into the low-level fitting routines, we define a collection of functions which
+ * allow us to abstract this type of model-dependent information. These generic
+ * functions take the model type and return the corresponding function pointer
+ * for the specified model. Each model is defined by creating this collection of
+ * specific functions, and placing them in a single file for each model. We
+ * define the following structure to carry the collection of information about
+ * the models.

+ * sources with measured moments for a group with moments which are all very
+ * similar. The function returns a pmPSFClump structure, representing the
+ * centroid and size of the clump in the sigma_x, sigma_y second-moment plane.
+ *
+ * The goal is to identify and characterize the stellar clump within the
+ * sigma_x, sigma_y second-moment plane.  To do this, an image is constructed to
+ * represent this plane.  The units of sigma_x and sigma_y are in image pixels. A
+ * pixel in this analysis image represents 0.1 pixels in the input image. The
+ * dimensions of the image need only be 10 pixels. The peak pixel in this image
+ * (above a threshold of half of the image maximum) is found. The coordinates of
+ * this peak pixel represent the 2D mode of the sigma_x, sigma_y distribution.
+ * The sources with sigma_x, sigma_y within 0.2 pixels of this value are then
+ *  * used to calculate the median and standard deviation of the sigma_x, sigma_y
+ * values. These resulting values are returned via the pmPSFClump structure.

+ *
+ *  @brief Contains the tests for pmFlatField.c:
+ *
+ *    Test A - Divide input image by flat image
+ *    Test B - Mask flat image data
+ *    Test C - Mask flat image data starting with non-null mask
+ *    Test E - Attempt to use null input image
+ *    Test F - Attempt tp use null flat image
+ *    Test G - Attempt to use input image bigger than flat image
+ *    Test H - Attempt to use input image mask bigger than flat image
+ *    Test I - Attempt to use offset greater than input image
+ *    Test J - Attempt to use complex input image
+ *    Test K - Attempt to use complex flat image
+ *    Test L - Attempt to use non-equal input and flat image types
+ *    Test M - Attempt to use non-mask type mask image
+ *
+ * XXX: Added a mask argument to pmFlatField().  Must add tests.  For now, all
+ * masks are NULL.
+ *
+ *  @author Ross Harman, MHPCC
+ *
+ *  XXX: I added the CELL.TRIMSEC region code but there are not tests for it.

+ *  @author GLG, MHPCC
+ *
+ * XXX: Must test
+ *       pmSourceRoughClass

+ *
+ *
+ * XXX: Must test output results for many other functions.
+ *
+ * XXX: There are many cases where row/col can be switched in the code.
+ * We must test that here by using non-square images.  All tests
+ * in this file should be run with non-square images.

+ * XXX: Memory leaks are not being caught.  If I allocated a psVector in these functions

+ *
+ * XXX: Much of this file is commented out due to the API changes in rel 7.

+NAME
+     tap -- write tests that implement the Test Anything Protocol
+
+SYNOPSIS
+     #include <tap.h>
+
+DESCRIPTION
+     The tap library provides functions for writing test scripts that produce
+     output consistent with the Test Anything Protocol.  A test harness that

+.Dd December 20, 2004
+.Os
+.Dt TAP 3
+.Sh NAME
+.Nm tap
+.Nd write tests that implement the Test Anything Protocol
+.Sh SYNOPSIS
+.In tap.h
+.Sh DESCRIPTION
+The
+.Nm
+library provides functions for writing test scripts that produce output
+consistent with the Test Anything Protocol.  A test harness that parses
+this protocol can run these tests and produce useful reports indicating
+their success or failure.
+.Ss PRINTF STRINGS
+In the descriptions that follow, for any function that takes as the
+last two parameters
+.Dq Fa char * , Fa ...
+it can be assumed that the
+.Fa char *
+is a
+.Fn printf
+-like format string, and the optional arguments are values to be placed
+in that string.
+.Ss TEST PLANS
+.Bl -tag -width indent
+.It Xo
+.Ft int
+.Fn plan_tests "unsigned int"
+.Xc
+.It Xo
+.Ft int
+.Fn plan_no_plan "void"
+.Xc
+.It Xo
+.Ft int
+.Fn plan_skip_all "char *" "..."
+.Xc
+.El
+.Pp
+You must first specify a test plan.  This indicates how many tests you
+intend to run, and allows the test harness to notice if any tests were
+missed, or if the test program exited prematurely.
+.Pp
+To do this, use
+.Fn plan_tests ,
+which returns the number of planned tests.  The function will cause
+your program to exit prematurely if you specify 0 tests.
+.Pp
+In some situations you may not know how many tests you will be running, or
+you are developing your test program, and do not want to update the
+.Fn plan_tests
+parameter every time you make a change.  For those situations use
+.Fn plan_no_plan .
+It returns 1, and indicates to the test harness that an indeterminate number
+of tests will be run.
+.Pp
+Both
+.Fn plan_tests
+and
+.Fn plan_no_plan
+will cause your test program to exit prematurely with a diagnostic
+message if they are called more than once.
+.Pp
+If your test program detects at run time that some required functionality
+is missing (for example, it relies on a database connection which is not
+present, or a particular configuration option that has not been included
+in the running kernel) use
+.Fn plan_skip_all ,
+passing as parameters a string to display indicating the reason for skipping
+the tests.
+.Ss SIMPLE TESTS
+.Bl -tag -width indent
+.It Xo
+.Ft unsigned int
+.Fn ok "expression" "char *" "..."
+.Xc
+.It Xo
+.Ft unsigned int
+.Fn ok1 "expression"
+.Xc
+.It Xo
+.Ft unsigned int
+.Fn pass "char *" "..."
+.Xc
+.It Xo
+.Ft unsigned int
+.Fn fail "char *" "..."
+.Xc
+.El
+.Pp
+Tests are implemented as expressions checked by calls to the
+.Fn ok
+and
+.Fn ok1
+macros.  In both cases
+.Fa expression
+should evaluate to true if the test succeeded.
+.Pp
+.Fn ok
+allows you to specify a name, or comment, describing the test which will
+be included in the output.
+.Fn ok1
+is for those times when the expression to be tested is self
+explanatory and does not need an associated comment.  In those cases
+the test expression becomes the comment.
+.Pp
+These four calls are equivalent:
+.Bd -literal -offset indent
+int i = 5;
+
+ok(i == 5, "i equals 5");      /* Overly verbose */
+ok(i == 5, "i equals %d", i);  /* Just to demonstrate printf-like
+                                  behaviour of the test name */
+ok(i == 5, "i == 5");          /* Needless repetition */
+ok1(i == 5);                   /* Just right */
+.Ed
+.Pp
+It is good practice to ensure that the test name describes the meaning
+behind the test rather than what you are testing.  Viz
+.Bd -literal -offset indent
+ok(db != NULL, "db is not NULL");            /* Not bad, but */
+ok(db != NULL, "Database conn. succeeded");  /* this is better */
+.Ed
+.Pp
+.Fn ok
+and
+.Fn ok1
+return 1 if the expression evaluated to true, and 0 if it evaluated to
+false.  This lets you chain calls from
+.Fn ok
+to
+.Fn diag
+to only produce diagnostic output if the test failed.  For example, this
+code will include diagnostic information about why the database connection
+failed, but only if the test failed.
+.Bd -literal -offset indent
+ok(db != NULL, "Database conn. succeeded") ||
+    diag("Database error code: %d", dberrno);
+.Ed
+.Pp
+You also have
+.Fn pass
+and
+.Fn fail .
+From the Test::More documentation:
+.Bd -literal -offset indent
+Sometimes you just want to say that the tests have passed.
+Usually the case is you've got some complicated condition
+that is difficult to wedge into an ok().  In this case,
+you can simply use pass() (to declare the test ok) or fail
+(for not ok).
+
+Use these very, very, very sparingly.
+.Ed
+.Pp
+These are synonyms for ok(1, ...) and ok(0, ...).
+.Ss SKIPPING TESTS
+.Bl -tag -width indent
+.It Xo
+.Ft int
+.Fn skip "unsigned int" "char *" "..."
+.Xc
+.It Xo
+.Fn skip_start "expression" "unsigned int" "char *" "..."
+.Xc
+.It Xo
+.Fn skip_end
+.Xc
+.El
+.Pp
+Sets of tests can be skipped.  Ordinarily you would do this because
+the test can't be run in this particular testing environment.
+.Pp
+For example, suppose some tests should be run as root.  If the test is
+not being run as root then the tests should be skipped.  In this 
+implementation, skipped tests are flagged as being ok, with a special
+message indicating that they were skipped.  It is your responsibility
+to ensure that the number of tests skipped (the first parameter to
+.Fn skip )
+is correct for the number of tests to skip.
+.Pp
+One way of implementing this is with a
+.Dq do { } while(0);
+loop, or an
+.Dq if( ) { } else { }
+construct, to ensure that there are no additional side effects from the
+skipped tests.
+.Bd -literal -offset indent
+if(getuid() != 0) {
+        skip(1, "because test only works as root");
+} else {
+        ok(do_something_as_root() == 0, "Did something as root");
+}
+.Ed
+.Pp
+Two macros are provided to assist with this.  The previous example could
+be re-written as follows.
+.Bd -literal -offset indent
+skip_start(getuid() != 0, 1, "because test only works as root");
+
+ok(do_something_as_root() == 0, "Did something as root");
+
+skip_end();
+.Ed
+.Ss MARKING TESTS AS Dq TODO
+.Bl -tag -width indent
+.It Xo
+.Ft void
+.Fn todo_start "char *" "..."
+.Xc
+.It Xo
+.Ft void
+.Fn todo_end "void"
+.Xc
+.El
+.Pp
+Sets of tests can be flagged as being
+.Dq TODO .
+These are tests that you expect to fail, probably because you haven't
+fixed a bug, or finished a new feature yet.  These tests will still be
+run, but with additional output that indicates that they are expected
+to fail.  Should a test start to succeed unexpectedly, tools like
+.Xr prove 1
+will indicate this, and you can move the test out of the todo
+block.  This is much more useful than simply commenting out (or
+.Dq #ifdef 0 ... #endif )
+the tests.
+.Bd -literal -offset indent
+todo_start("dwim() not returning true yet");
+
+ok(dwim(), "Did what the user wanted");
+
+todo_end();
+.Ed
+.Pp
+Should
+.Fn dwim
+ever start succeeding you will know about it as soon as you run the
+tests.  Note that
+.Em unlike
+the
+.Fn skip_*
+family, additional code between
+.Fn todo_start
+and
+.Fn todo_end
+.Em is
+executed.
+.Ss SKIP vs. TODO
+From the Test::More documentation;
+.Bd -literal -offset indent
+If it's something the user might not be able to do, use SKIP.
+This includes optional modules that aren't installed, running
+under an OS that doesn't have some feature (like fork() or
+symlinks), or maybe you need an Internet connection and one
+isn't available.
+
+If it's something the programmer hasn't done yet, use TODO.
+This is for any code you haven't written yet, or bugs you have
+yet to fix, but want to put tests in your testing script 
+(always a good idea).
+.Ed
+.Ss DIAGNOSTIC OUTPUT
+.Bl -tag -width indent
+.It Xo
+.Fr unsigned int
+.Fn diag "char *" "..."
+.Xc
+.El
+.Pp
+If your tests need to produce diagnostic output, use
+.Fn diag .
+It ensures that the output will not be considered by the TAP test harness.
+.Fn diag
+adds the necessary trailing
+.Dq \en
+for you.
+.Bd -literal -offset indent
+diag("Expected return code 0, got return code %d", rcode);
+.Ed
+.Pp
+.Fn diag
+always returns 0.
+.Ss EXIT STATUS
+.Bl -tag -width indent
+.It Xo
+.Fr int
+.Fn exit_status void
+.Xc
+.El
+.Pp
+For maximum compatability your test program should return a particular
+exit code.  This is calculated by
+.Fn exit_status
+so it is sufficient to always return from
+.Fn main
+with either
+.Dq return exit_status();
+or
+.Dq exit(exit_status());
+as appropriate.
+.Sh ENVIRONMENT
+The following environment variables affect
+.Nm .
+.Bl -tag -width indent
+.It Ev HARNESS_ACTIVE
+Causes an extra
+.Dq \en
+to be printed before any diagnostic failure output generated by
+.Nm .
+This variable is normally set if tests are being run under Perl's
+Test::Harness.
+.El
+.Sh EXAMPLES
+The
+.Pa tests
+directory in the source distribution contains numerous tests of
+.Nm
+functionality, written using
+.Nm .
+Examine them for examples of how to construct test suites.
+.Sh COMPATABILITY
+.Nm
+strives to be compatible with the Perl Test::More and Test::Harness 
+modules.  The test suite verifies that
+.Nm
+is bug-for-bug compatible with their behaviour.  This is why some
+functions which would more naturally return nothing return constant
+values.
+.Pp
+If the
+.Lb libpthread
+is found at compile time,
+.Nm
+.Em should
+be thread safe.  Indications to the contrary (and test cases that expose
+incorrect behaviour) are very welcome.
+.Sh SEE ALSO
+.Xr Test::More 1 ,
+.Xr Test::Harness 1 ,
+.Xr prove 1
+.Sh STANDARDS
+.Nm
+requires a
+.St -isoC-99
+compiler.  Some of the
+.Nm
+functionality is implemented as variadic macros, and that functionality
+was not formally codified until C99.  Patches to use
+.Nm
+with earlier compilers that have their own implementation of variadic
+macros will be gratefully received.
+.Sh HISTORY
+.Nm
+was written to help improve the quality and coverage of the FreeBSD
+regression test suite, and released in the hope that others find it
+a useful tool to help improve the quality of their code.
+.Sh AUTHORS
+.An "Nik Clayton" Aq nik@ngo.org.uk ,
+.Aq nik@FreeBSD.org
+.Pp
+.Nm
+would not exist without the efforts of
+.An "Michael G Schwern" Aq schqern@pobox.com ,
+.An "Andy Lester" Aq andy@petdance.com ,
+and the countless others who have worked on the Perl QA programme.
+.Sh BUGS
+Ideally, running the tests would have no side effects on the behaviour
+of the application you are testing.  However, it is not always possible
+to avoid them.  The following side effects of using
+.Nm
+are known.
+.Bl -bullet -offset indent
+.It
+stdout is set to unbuffered mode after calling any of the
+.Fn plan_*
+functions.

+
+I am testing a new concept for the 2D representation of various values
+measured by psphot.  I have been using 2D polynomials to fit the
+variations of, eg, the psf parameters as a function of position in the
+images.  this has been somewhat successful, but it has also been
+fraught with a number of problems.  the worst issue has been the fact
+that the polynomial form is not physically motivated.  in some cases,
+eg the variation of the psf shape parameters, the true variations for
+real distributions are not well represented by a polynomial.  I have
+done some ad hoc tricks to get the functional form to look roughly
+like a polynomial, but this is really quite a hack.  the other problem
+is that it is difficult to decide if the polynomial does an acceptable
+job representing the variations.
+
+My new concept for modeling 2D variations in some parameter is to
+define a low-resolution 2D image to represent the variation.  The
+advantage is that the image may be define with whatever resolution may
+be sampled by the input data, and the functional form need not be
+constrained by the polynomial basis function.  
+
+** is this a poor substitute for using a chebychev polynomial as a
+   better basis function?

+2007.08.17
+
+ I am working on a number of cleanup / fixes.  I have made an overhaul
+ of the pmModel APIs, adding function pointers in the pmModel
+ structure to the class-specific utility functions (eg,
+ pmModel->modelFunc is the actual function which is evaluated). 
+
+ TO DO:
+
+ * update pmSourceFitSet to be able to include more than one model
+   type (currently it assumes the sources are all, eg, PSFs).  This is
+   now needed because the old implementation used the function lookups
+   which have been dropped.
+
+ * define a generic API set to handle 2D modelling of a scalar using
+   either polynomials (as the pmPSF code currently does) or an
+   image-based representation (as the psphot sky model currently
+   does).  
+
+   The image-based representation can automatically step down from NxM
+   super pixels to a smaller number based on the density of
+   measurements.  
+
+   Include ways to smooth and regularize the output result.
+
+   This mechanism can be applied to: psf parameters, aperture
+   residual, psf peak-to-flux variations, the psphot background
+   representation.
+
+ * generate and store the output radial profile for objects
+
+ * finish testing and incorportate the CR / EXT measurements
+
+ * adjustments to pixel center based on second derivatives : needed
+   for the sersic models.
+
+ * adjustments to pixel flux for extreme values (r ~ 0) : needed for
+   the sersic models.
+
+ * on psf stars : fall back on a Gaussian.
+
+ * OPTIMIZATIONS !!
+
+ * drop the model sky element : should only be in source->sky,dsky
+
+2006.11.16
+
+ensemble:
+
+  * first block: 
+    * select sources of interest / skip
+    * generate a guess model
+    * re-measure moments for saturated stars (MOVE)
+    * update peak position (MOVE to peaks)
+    * set the object radius 
+    * build temporary source copies (including pixels, mask, weight)
+
+  * second block:
+    * measure the cross-products and weights
+    * add to the sparse matrix
+
+  * build full-image mask
+  * measure coord weights
+  * build order elements
+
+  * solve for source amplitudes
+  * update models
+
+  * create psSparseBorder to solve matrix equations which have a large
+    sparse region, with a completely filled border of a smaller number
+    of rows.
+
+  * trying to modify psphotEnsemble to (1) be more general (not just
+    PSFs) and (2) fit for the sky offset.
+
+    - how is the radius for each source set?
+    
+
+2006.11.11
+
+  I am trying to define a complete set of tests to validate the
+  measurement of the photometry compared with the simulated images.
+  Part of my confusion is controlling exactly which corrections are
+  applied to the output magnitudes.  Here is the complete list:
+
+  psfMag_out = psfMag_meas + ApTrend(x,y,0.0,0.0)
+  apMag_out = apMag_meas + growth(radius,refRadius) + f(skyBias,skySat)
+
+  these corrections are modified by the following config settings:
+
+  IGNORE_GROWTH (sets all growth magnitudes to the fitMag value,
+  effectively turning off the growth correction)
+
+  APTREND : set the level of correction
+    NONE     : no correction is fitted
+    CONSTANT : just a single constant (applied to get psfMag_out)
+    SKYBIAS  : the skybias term is fitted (constant applied to psfMag,
+               slope applied apMag)
+  
+2006.11.08
+
+  I have been testing the pmSourceMagnitudes interpolation of the
+  source position when measuing the aperture magnitudes.  I built a
+  test suite for pmSourceMagnitudes and pmGrowthCurve.  even with
+  bicubic interpolation, there are noticable errors for small
+  apertures (ie, small compared to the PSF sigma).  I used a gaussian
+  PSF to make the tests.  it seems that, if the radius is less than 2
+  sigma or so, the interpolated aperture mag is in error by as much as
+  12mmag.  The size of this effect must depend on the smoothing
+  algorithm, the shape of the PSF, the size of the PSF relative to the
+  pixels, and the size of the subpixel interpolation.  I believe the
+  effect is a result of the smoothing introduced by the interpolation:
+  the smoothing pushes the flux in the inner portions of the PSF down
+  and enhances the flux in the outer portions.  thus, there is
+  actually a turn over in the error: at very large values, the error
+  is very small because the aperture contains all of the flux, and the
+  interpolation has little effect.  as the radius shrinks, the error
+  grows (in the sense of M_raw - M_interpolated; ie, the flux in the
+  interpolated source is too large).  around 2-3sigma, the error turns
+  over and becomes negative (too little flux in the interpolated
+  source). 
+
+  The sigmas I used for these tests (1.0, 1.5, 2.0 pix) are
+  appropriate for the range we expect to see from PS1, or any
+  well-sampled detector.  Thus, even though the effect is probably
+  less important for poorer seeing, we have to be careful to avoid it
+  in our Pan-STARRS analysis.
+
+  Currently, the minimum aperture is defined only by the config
+  variable PSF_FIT_PAD, which really implies a padding.  My proposal
+  is to require the minimum aperture to be a number of sigma (an
+  additional parameter).  Then, the formula for the radius would be
+  something like:
+
+  MAX (modelRadiusPSF (PSF_FIT_NSIGMA), PSF_FIT_RADIUS_NSIG) +

+
+  I have added the aperture interpolation as a component of the
+  pmSourceMagnitudes function.  
+
+  I am trying to make things a bit more organized, with more
+  consistent APIs. 
+
+  * changed pmPSFtry to use the pmSourceMagnitudes API
+  * changed pmPSFtry to use new pmSource entries for each try (saving
+  * the pmModels generated)
+
+  other notes:
+  * moved psphotGrowthCurve -> pmGrowthCurveGenerate 
+

+  * measure bicube fit to peak from smoothed image
+  * use psphotEnsemble fit to re-measure normalization?
+  * extended object statistical measures

+
+  Looking into the growth curve problem.  RHL sent his recipe for
+  correcting to true circular apertures.  I've done a test fix of
+  interpolating the stellar image to the desired center.  it looks
+  like bilinear interpolation is insufficient (about 8% error for 2
+  pixel radius aperture).  Unless I've got the formula wrong, the
+  effective smoothing of the gaussian is moving flux from the center
+  out and making small apertures in error that depends on the offset.
+  Bicubic could be enough to clean this up?  
+
+  I think the current code may need to be careful modified to include
+  the interpolation for every aperture measurement.  there are paired
+  'pmModelAdd' and pmModelSub steps to add and remove the model flux.
+  I need to be careful about how the mask affects these steps.
+
+  I also need to be careful in interpreting the test results: since
+  the simulated images create objects by filling in a pixel and then
+  smoothing, all objects have centroids which are exactly 0.5 pixel
+  offsets.  These all then have a fixed growth correction error, which
+  fortunately happens to be substantial (because of a 0.5 pixel offset
+  in the growth curve reference object!)
+
+  I need to double check the 0.5 pixel error issues.  There are
+  problems with the pslib version of psImageShift and
+  psImageInterpolate (or at least inconsistencies).  the pmModelAdd
+  and Sub functions and the centroid functions are probably also
+  inconsistent.
+
+2006.11.01
+
+  Trying to understand low-level errors in psphot using simulated
+  data.  the main issue I am concerned with is the bias RHL is seeing
+  in SDSS-psphot comparisons.  But there are other issues that are
+  creeping in and probably point at logical errors in the code.
+
+  * in pmPSFtry, I measure the first pass on the aperture residual (to
+    choose between PSF model options, if that is being tested).  This
+    analysis currently uses a polynomial fit (1st order) for the offset
+    and the sky bias (using r^2/flux as an independent variable).
+
+    Notes:
+
+    - is the psf-fit error distribution reasonable?  perhaps a little
+      on the high side: at 10000 DN, noise is 0.0138, should be
+      0.0107.
+
+    - scatter of ap-fit is surprisingly high.  M_input - M_fit has a
+      median chisq of 2 (mean of 5), while M_input - M_ap has a median
+      chisq of 125 (mean of 380).  This is using a radius of 15.  It
+      cleans up hugely when I go to a radius of 7 and even more so
+      with radius = 4. (In this case, the PSF sigma is 1.5, so 4 is
+      well matched and 7 is only slightly large).
+
+      * make the initial PSF fitting radius and aperture radius
+	  different?  
+      * make the initial PSF fitting radius a function of the measured
+	  PSF sigma?
+
+    - I have been fitting ap-fit mag without weights; the resulting
+      ap-fit errors are highly over-estimated since the ap-fit scatter
+      is too high.  I have added code to carry the weights (error from
+      the fit only at the moment, ie, not the ap error as well).  This
+      is good, but not as important if the radius is chosen well above.
+
+  * a bias in the psphotEnsemble results depending on the sky level
+    but not in the PSF model fits?  turning on/off CONST_PHOT_WT has
+    an equivalent effect, but is quite small.  why is one sensitive to
+    the sky and the other is not?  
+
+  * the error measured by psphotEnsemble was wrong (and inconsistent
+    for a given weighting situation): fixed the def of the error.
+
+  * still trying to understand the corrections being made.  running a
+    few tests:
+
+    keeping PSF_FIT_RADIUS at 4.0
+
+    t1 : no growth correction,    constant weights
+    t2 :    growth correction,    constant weights
+    t3 : no growth correction, no constant weights
+    t4 :    growth correction, no constant weights
+    t5 :    growth correction,    constant weights, constant ap (4)
+    t6 :    growth correction,    constant weights, integer radius
+    t7 :    growth correction,    constant weights, integer radius
+    (for t7, I've fixed the bug that the growth correction include the
+    min radius).
+
+  * psphotGrowthCurve is messed up : the measurement does not correct
+    for the actual object center, and at small radii this is an
+    important source of noise.
+
+2006.06.28
+
+  I am adding a few minor features.  First up is the ability to break
+  the processing at interesting stages.  These will be:
+
+  - PEAKS: after sources are generated, but before moments are
+    measured
+  - MOMENTS: after moments are measured, before the PSF is measured
+  - PSFMODEL: after the psf model is measured, before sources are
+    fitted in bulk
+  - ENSEMBLE: after the linear ensemble fitting
+  - DEFAULT: complete processing
+
+2006.04.22
+
+  I have updated psphot to work with the cycle 11 release of psLib and
+  psModules.  At this point, the IfA group is now working off of the
+  CVS head rather than from a separate IfA branch of psLib and
+  psModules.  The cycle 11 release of psLib needed a few updates to
+  fix minor problems.  The psModules code needed significant work to
+  fix discrepancies.  The new version of psphot has also been leak
+  checked, at least for basic configurations.  This new version of
+  psphot should be used with the new camera configuration system,
+  which can be found in the ipp/config directory.  Here are the
+  necessary tags:
+
+  psphot: psphot_dev_11_0
+  psModules: rel11_ifa_pre0
+  psLib: rel11_ifa_0
+
+2006.04.16
+
+  Examining some of the throughput issues.  the flux measurement speed
+  is strongly dependent on the interation of the function step size:
+
+  dz = 0.01 : 3.24s for 4400 objects
+  dz = 0.1  : 0.44s for 4400 objects
+
+  there is an increased error in the result with the larger step size,
+  but it is smaller than the phot error.  Still, we could do better
+  with a smarter integration function.
+
+  Including the aperture photometry on all sources, but not the
+  pixWeight, the source magnitudes takes 4.8 sec for 4400 objects.
+
+  Adding the pixWeight increases the time to 7.5 sec for 4400 objects
+
+2006.02.12
+
+  Last week, I made a new tag (psphot_dev_08) after finishing the work
+  to clean memory leaks and to modify psphot to work with Paul's
+  ppImage infrastructure.  
+
+  I have added a new background model function which generates a
+  median map based on Robert's suggestion of a) half-step windows and
+  b) linear interpolation.
+
+  Now, I am working to remove the constant sky level concepts and make
+  every relevant test use the signal/noise ratio as the trigger.  This
+  has impacts on the peak detections, the threshold for blends, and
+  the threshold for choosing pixels in the fitting routines.
+
+2005.12.23
+
+  Improvements in psphot as of psphot_dev_07
+
+  - updated to work with psModule release 9.0
+  - moved model test functions into psphot as optional mode
+  - added pmSourceFitSet : simultaneous model group fitting
+  - added bicubic interpolation to tweak up the peak coordinates
+  - added aperture residual analysis after complete object model & subtraction
+  - added 3D (x,y,rflux) aperture residual fitting
+  - added blend vs blob fitting (BlendFit)
+  - added ensemble PSF fitting, with sparse matrix inversion
+  - improved the flagging / marking of model results
+  - better abstraction for setting fit parameters
+  - various low-level fixes
+  - added PSF output option
+  - added break points
+  - added more optional output formats
+  - fixed FITS table output
+
+  Things still to be added to psphot:
+
+  - better initial background model (NxM median grid?)
+  - include local background model in EnsemblePSF Fit (use sparse matrix)
+  - 2nd pass (after object subtraction) to smooth and detect faint objects
+  - re-add background to object-subtracted image
+  - cleanup function names
+  - push more functions into psLib / psModule
+  - fix extended / galaxy models to improve stability
+  - add mode with input PSF
+  - add mode with input fixed sources (PS_SOURCE_FIXED)
+  - cleanup memory leaks
+
+2005.11.25
+
+  I've updated psphot to work with the current psLib v8, though a
+  number of psLib fixes were needed.  These are pushed under
+  psLib:eam_rel8_b2.  The psphot code which works with that version of
+  psLib is tagged psphot_dev_04.
+
+  I'm working on converting psphot to work with the current release of
+  psModules, which basically includes all of the object functions. 
+
+  - change comments are relative to psModules (vs psphot versions)
+
+  psEllipse.c : OK
+  psEllipse.h : OK
+  pmModelGroup.c : OK (missing TGAUSS entry)
+  pmModelGroup.h : OK (adds many comments)
+
+  pmPSFtry.c : a bunch of formatting weirdness (try-> got line breaks

+
+  psLibUtils.[ch] should be dropped from psModules
+  psModulesUtils.[ch] should be dropped from psModules
+
+  Makefile.am : dropped psModulesUtils.[ch], psLibUtils.[ch]
+
+  - I have successfully tested psphot with the psModules.v8 code
+    (eam_rel8_b1 tag).  I only needed to make a few modes in the
+    psModules code.  
+
+2005.11.16
+
+  I have made some fixes to make psphot work with pslib rel8_0.  I
+  need to merge psphot with the rel8_0 version of the psMinimize and
+  pmObjects code.  
+
+2005.09.06
+
+  I have built a working version of PSPhot using my own copy of the
+  pmObjects.[ch] files.  I need to minimize the difference between the
+  v0.7.0, v0.5.0, and my own version of pmObjects.c
+
+  additions to psLib based on the new version:
+  - extended the minimization to include parameter limits
+
+  changes v0.5.0 / v0.7.0 / EAM
+  - changed all ps* to pm*
+  - fixed naming for local static functions (eg modelFree not p_psModelFree)
+  - dropped all hard-coded model names (vs v0.7.0)
+  - using current psMemSetDellocator name
+  - added noise image to pmSource
+  - converted old asserts to new asserts (PS_.._CHECK..)
+  - add return from error in pmFindImagePeaks
+  - allow isItInThisRegion to have NULL region (true)
+  - fixed subImages to correspond to region definition (end is
+    exclusive) in LocalSky and SetPixelCircle
+  - dropped old, redundant code in pmSourceLocalSky
+  - fixed pmSourceMoments use of mask (0 is valid, not 1)
+  - added pmSourceMoments validity tests (numPixels, Sum, centroid shift)
+  - added correction for Sxy (XY/Sum - x*y)
+  - added pmSourcePSFClump function (and pmPSFClump structure)
+  - allow missing sources in pmSourcePSFClump (not all peaks yield
+    sources)
+  - moved pmSourceRoughClass metadata lookups out of inner loop
+  - added saturated pixel test using pmImageCountPixelMask
+  - various redefinitions of initial classes
+  - dropped old, redundant code in pmSourceSetPixelsCircle
+  - mask image set to type psU8 (was psF32)
+  - abstract object model functions for pmSourceModelGuess
+  - converted evalModel to a public function psModelEval, modified params
+  - pmSourceFitModel operates on a specified model
+  - pmSourceFitModel had option to apply/ignore PSF information
+  - pmSourceFitModel calculates yErr
+  - pmSourceFitModel calculates the covariance matrix
+  - added paramMask to pmSourceFitModel 
+  - pmSourceFitModel_EAM uses covar to carry in beta and param
+    limits...
+  - pmSourceFitModel requires solution to stay within image
+  - pmSourceFitModel calculates and saves chisq, nIter, nDOF
+  - pmSourceFitModel uses GaussNewtonDelta for frozen params
+  - added mask to pmSourceAdd, pmSourceSub
+  - model abstractions in pmSourceAdd, pmSourceSub
+  - fixed 'center' option in pmSourceAdd/Sub
+
+  - pmPSF params should be F64
+
+  lingering concerns:
+  - Polynomials and related functions are STILL messed up.  this is a
+    major priority!!!
+  - pmSourceFitModel calculates sqrt(var), psMinimize calculates sq(sqrt(var))
+  - does psImageAlloc zero the image?  if so, drop init routine
+    from pmSourcePSFClump
+  - pmSourceRoughClass uses RDNOISE, GAIN to calculate SN: should use
+    the source->noise image? part of pmSourceMoments?
+  - pmSourceMoments_EAM uses macro for checkRegion
+  - pmObjects_EAM.c uses some hardcoded mask values (LocalSky)
+  - why does LocalSky_EAM not need subImageMask->col0 = subImage->col0??
+  - psGetRowVectorFromImage should be in psLib (in psLibUtils)
+  - pmSourceSetPixelsCircle and pmSourceLocalSky probably could use
+    the psImageMaskRegion, etc functions.
+  - pmSourceSetPixelsCircle uses a hard-coded mask value
+  - define a mask registration process??
+  - pmSourceContour is using the model flux, not the image flux
+
+2005.09.05
+
+  I have a working version of PSPhot which handles PSF and galaxy
+  models.  I am tagging the module with an alpha version number. this
+  version compiles with psLib-0.5.0, at least my version of it.  My
+  current goal is to make it work with the current psLib head (nearly
+  0.7.0) with a mimimum of _EAM versions of functions.
+
+  the tag for the working version is dev_01
+
+2005.06.04
+
+  progress on psphot has moved along well.  At this point, the process
+  loads the image, finds the peaks, determines a best PSF model,
+  identifies objects which are consistent with that model, and
+  attempts to fit a galaxy model to the objects which are not
+  consistent with the model. 
+
+  a variety of minor issues remain, as well as some major issues. 
+
+  - use a proper noise image to keep the fits honest after other
+    objects have been subtracted.  
+
+  - define the masks in terms of a single mask image.  this image
+    could be provided initially by the user.   
+
+  - add noise enhancement (couple with mask marking subtraction)

+2006.10.27
+
+  I have been working to fix the PSF modeling in psphot.  The PSF
+  model consists of a flux model for an individual object using an
+  analytical model with a number of parameters.  For a collection of
+  PSF objects, the variation of the parameters as a function of
+  position are then themselves fitted with a model.  The PSF model for
+  a single object consists of a radial profile with a functional form
+  f(z) where a given value of z defines an elliptical coutour of the
+  form z = \frac{x^2}{2\sigma_x^2} + \frac{y^2}{2\sigma_y^2} +
+  \sigma_{xy}xy.
+
+
+
+  The term \sigma_{xy} is difficult to model as a simple function of x
+  and y (eg, a low-order polynomial).  
+
+  A better model can be constructed for
+  \frac{\sigma_{xy}}{(\sigma_x^{-2} + \sigma_y^{-2})^2}, which varies
+  like a^2 \sin 2\theta

+***** one ambiguity: if we have a subimage, but we do not have the
+      parent image data (subimage does not carry dimensions of parent
+      array), then a 0 or negative upper-edge of a region cannot be
+      defined relative to the parent. we can specify it relative to
+      the subimage.  so, for example, given a subimage [32,100:32,100]
+      of a much larger image, then psRegionForImage with 0,0,0,0 as
+      input would return a region with values 32,100:32,100...

+
+*** things I've modified

+2006.02.02
+  I'm tagging psphot after I updated it to work with the readouts
+  using the structures being used for ppImage.  In this release, I
+  have also moved to autoconf for psphot, and the psphotReadout
+  portion is being defined as a library against which the other
+  elements are linked.  It should be possible to use this library with
+  ppImage, but I have not yet tested that.  
+
+  link psphot_dev_08 against psLib:eam_rel9_b2 and
+  psModule:eam_rel9_b2.
+
+2006.01.18
+  the tag below (psphot_dev_07) was moved to a later release.  It
+  should be used with psLib:eam_rel9_b1 from 2006/1/18 and
+  psModule:eam_rel9_p0.  
+
+2005.12.23
+  psphot_dev_07 should be compiled against psLib:eam_rel9_b1 and
+  psModule:eam_rel9_b1.  This version now handles the ensemble PSF
+  fitting, detection of blended sources, fitting of 'blends' (groups
+  of PSFs with distinct be 'blended' peaks) and 'blobs' (unresolved
+  extended objects, with a test for double PSF vs extended source
+  model.
+
+2005.11.25
+
+  psphot_dev_05 should be compiled against psLib tag eam_rel8_b2 and
+  psModules tag eam_rel8_b1.  this version removes all _EAM versions
+  of psLib and psModules code.  It now uses the psModules version of
+  the object code.
+
+  psphot_dev_04 should be compiled against psLib tag eam_rel8_b2 this
+  version removes all _EAM versions of psLib code, so that it is now
+  consistent with psLib.v8 (fixes are pushed into the eam_rel8_b2
+  branch).
+
+2005.11.16
+
+  psphot_dev_03 should be compiled against psLib tag eam_rel8_b1, a
+  branch starting from psLib rel8_0.  I needed to make some minor
+  fixes in psLib to work successfully with psLib rel8_0.
+
+  psphot_dev_02 was getting segfaults from a bug added into psLib in
+  rel8_0 in p_psVectorClippedStats.  I also fixed some errors arising
+  from changing types (argument to psMetadataParseConfig).

+ * the meaning of the parameter.  The meaning of the parameters may thus vary depending on the
+ * specifics of the model.  All models which are used a PSF representations share a few
+ * parameters, for which # define names are listed in pmModel.h:
+
+ * PM_PAR_SKY 0   - local sky : note that this is unused and may be dropped in the future
+ * PM_PAR_I0 1    - central intensity
+ * PM_PAR_XPOS 2  - X center of object
+ * PM_PAR_YPOS 3  - Y center of object
+ * PM_PAR_SXX 4   - X^2 term of elliptical contour (sqrt(2) * SigmaX)
+ * PM_PAR_SYY 5   - Y^2 term of elliptical contour (sqrt(2) * SigmaY)

+- pswarp takes an image (and corresponding mask and weight images) and
+  warps the pixels to match the specified skycell projection and pixel
+  grid.  the astrometry of the input image is supplied by the header
+  of the image or by a specified SMP file. 
+
+- the input image, weight, mask are loaded into pmFPA structures with
+  the layout determined by the camera/format/layout
+
+- the skycell is loaded into a pmFPA structure.  at a minimum, a
+  single skycell may contain a single chip, cell, and readout, which
+  in turn correspond to the single set of pixels representing the
+  image region.  
+
+  * is there a need or use for a skycell to have a multilayered
+    structure equivalent in any way to the fpa->chip->cell->readout
+    layer?
+
+    - perhaps we will want to use a single fpa for a larger region
+      with small sky cells representing contiguous pixel regions.  
+
+    - perhaps we will want to warp an entire fpa exposure at once and
+      use a skyfpa to represent all of the possible output skycells
+      for a single input fpa exposure.
+
+- the output is a file or set of files corresponding to the skycell
+  files.  the details should be specified by the PSWARP.OUTPUT file
+  rule.
