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 -Dusershrplib is in effect,
7 # and by MacOS Classic.
8 #
9 # Reads from information stored in
10 #
11 #    config.h
12 #    config.sh
13 #    global.sym
14 #    globvar.sym
15 #    intrpvar.h
16 #    macperl.sym  (on MacOS)
17 #    miniperl.map (on OS/2)

19 #    perlio.sym
20 #    perlvars.h

22 # plus long lists of function names hard-coded directly in this script and
23 # in the DATA section.
24 #
25 # Writes the result to STDOUT.
26 #
27 # Normally this script is invoked from a makefile (e.g. win32/Makefile),
28 # which redirects STDOUT to a suitable file, such as:

30 #    perl5.def   OS/2
31 #    perldll.def Windows
32 #    perl.exp    AIX
