+=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 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`
