#MODULE build_prd_files
#
#***********************************************************************
"""

**PURPOSE** --
Fetch a list of elements from a PRDUVM library.
This module creates two lists, one containing all the elements
fetched and the other containing the log of the PRDUVM activities.


**DEVELOPER** --
k. clark

**MODIFICATION HISTORY** --

o Initial implementation 6/ 7/02
o Updated 8/ 1/03 KWC - Add numbering method.
o Updated 11/ 6/03 KWC - Increment line numbers by 10 instead of 1.
o Updated 12/ 3/03 KWC - Correct FD record count by /10.
o Updated 12/29/03 RSK - Added processing for collections and associated
tags
o Updated 03/12/04 RSK - Added method to format file without line numbers
o Updated 3/30/04 KWC - Changed module name to build_prd_files.
o Updated 4/ 9/04 KWC - Remove numbering and write methods.
