2#
3# Create the export list for perl.
4#
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.
8#
9# Reads from information stored in
10#
11# %Config::Config (ie config.sh)
12# config.h
13# embed.fnc
14# globvar.sym
15# intrpvar.h
16# miniperl.map (on OS/2)
17# perl5.def (on OS/2; this is the old version of the file being made)
18# perlio.sym
19# perlvars.h
20# regen/opcodes
21#
22# plus long lists of function names hard-coded directly in this script.
23#
24# Writes the result to STDOUT.
25#
26# Normally this script is invoked from a makefile (e.g. win32/Makefile),
27# which redirects STDOUT to a suitable file, such as:
28#
29# perl5.def OS/2
30# perldll.def Windows
31# perl.exp AIX
32# perl.imp NetWare
33# makedef.lis VMS
