+
+  The calibration suite uses a database table of known/registered DVO
+  databases to be calibrated.  The suite operates on a segment of the
+  sky in each run, nominally a section ~1h west of the current ST.
+
+  caltool -pendingdbs returns a list of entries (mdc format), one for
+  each DVO database in the table.  
+
+  caltool -databases [-active] : returns the list of dvo databases
+  caltool -addcalrun : inserts the stats for a single calibration run
+  caltool -setstate (active/inactive) : modify the state of a dvo
+    database
+  caltool -adddatabase : insert a new database
+
+  XXX a potential source of collisions.  the books are marked by
+  unique keys in the db tables, but a single pantasks run may be
+  addressing multiple databases.  IDs are not unique across
+  databases.  we can solve this by including in the key the dbname
+
+  the calibration suite runs the following tasks, in sequences on each
+  of the databases:
+
+  * resort, relphot, uniphot, relastro.objects, relastro.images
+
+  ** detrend correction: any detrend images which need to be corrected
+     get inserted in the detCorrectedExp table.  
+
+  dettool commands needed:
+  * add a detrend exposure (det_id, exp_id) to the detCorrectedExp table
+  * add a detrend imfile (det_id, exp_id, class_id) to the
+  detCorrectedImfile table
+  * select pending detCorrectedExp
+  * select pending detCorrectedImfiles
