10# This script will translate any SYMBOL_VECTOR item that has a translation
11# in CXX$DEMANGLER_DB.  The latter is generated by and CC/DECC command that
12# uses the qualifier /REPOSITORY with the build directory as value.  When
13# /NAMES=SHORTENED has been used, this file will hold the translations from
14# the original symbols to the shortened variants.
15#
16# CXX$DEMAGLER_DB. is an ISAM file, but with the magic of RMS, it can be
17# read as a text file, with each record as one line.
18#
19# The lines will have the following syntax for any symbol found that's longer
20# than 31 characters:
21#
22# LONG_symbol_34567890123{cksum}$LONG_symbol_34567890123_more_than_31_chars
23#
24# $ is present at the end of the shortened symbol name, and is preceded by a
25# 7 character checksum.  The $ makes it easy to separate the shortened name
26# from the original one.
