 # Create the export list for perl.
 # Needed by AIX to do dynamic linking.
+#
+# This simple program relys on 'global.sym' and other *.sym files
+# being up to date with all of the global symbols that a dynamic
+# link library might want to access.
+#
+# Most symbols have a Perl_ prefix because that's what embed.h sticks
+# in front of them.  Variations depend on binary compatibility with
+# Perl 5.003.

-# NOTE: If you're using 'old_embed.pl', don't use this script!
-#       Use 'old_perl_exp.SH' instead.
