# NAME: updatefixdata
#
# DESCRIPTION: This program reads the internal table for this build 
#              cycle and finds every fileset name that corresponds to every 
#              apar that exists in the internal table.  This program builds 
#              the fixdata stanza for each apar from the set of fileset 
#              names that are found in the internal table as well as the 
#              abstract information in the abstract file for each apar.
#
#              Each line of the internal table has the format:
#              PTF fileset vrmf apar apar ...
#
#              This program will read through the entire internal table 
#              and build a temporary file.
#
#              Then, for each unique apar in the internal table, it will 
#              find the filesets and build the fixdata.  This program then
#              reads the fixdata database and appends stanzas to the 
#              database if they do not already exist.
#
# INPUT PARAMETERS: internal vrmf Table.
#                   abstracts file.
#
# OUTPUT: fixdata database
#
# SIDE EFFECTS: appends new fixdata stanzas to the fixdata database file
#
# RETURNS: None
