#./perl -w
#
# Create the export list for perl.
#
# Needed by WIN32 and OS/2 for creating perl.dll,
# and by AIX for creating libperl.a when -Duseshrplib is in effect,
# and by VMS for creating perlshr.exe.
#
# Reads from information stored in
#
# %Config::Config (ie config.sh)
# config.h
# embed.fnc
# globvar.sym
# intrpvar.h
# miniperl.map (on OS/2)
# perl5.def (on OS/2; this is the old version of the file being made)
# perlio.sym
# perlvars.h
# regen/opcodes
#
# plus long lists of function names hard-coded directly in this script.
#
# Writes the result to STDOUT.
#
# Normally this script is invoked from a makefile (e.g. win32/Makefile),
# which redirects STDOUT to a suitable file, such as:
#
# perl5.def OS/2
# perldll.def Windows
# perl.exp AIX
# perl.imp NetWare
# makedef.lis VMS
