+"""
+A command designed to do a one-time reformatting of DACT IDs and Fragment
+IDs in the database. 
+
+Fragment IDs should be of the form "F-XXXX" where XXXX is some alphanumeric.
+Fragment IDs are currently assumed to be in the form "F-XXXX" or "XXXX".
+DACT IDs should be of the form "D:0XXXX" where XXXX is the Fragment ID alphanumeric. 
+DACT IDs are currently assumed to be in the form "0XXXX" or  "D-0XXXX".
+
+This command simply adds the prefix "F-" to all Fragment IDs and "D:" to all
+DACT IDs where they are missing.
