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