5 # Needed by WIN32 and OS/2 for creating perl.dll,
6 # and by AIX for creating libperl.a when -Duseshrplib is in effect,
7 # and by VMS for creating perlshr.exe.

9 # Reads from information stored in
10 #

24 #
25 # Normally this script is invoked from a makefile (e.g. win32/Makefile),
26 # which redirects STDOUT to a suitable file, such as:

29 #    perldll.def Windows
30 #    perl.exp    AIX
