Okay, here's your official unofficial closure leak patch

[perl5.git] / minimod.PL

# minimod.PL writes the contents of miniperlmain.c into the module
# ExtUtils::Miniperl for later perusal (when the perl source is
# deleted)
#
# It also writes the subroutine writemain(), which takes as its
# arguments module names that shall be statically linked into perl.
#
# Authors: Andreas Koenig <k@franz.ww.TU-Berlin.DE>, Tim Bunce
#          <Tim.Bunce@ig.co.uk>

# Version 1.0, Feb 2nd 1995 by Andreas Koenig

print <<'END';
# This File keeps the contents of miniperlmain.c.
#
# It was generated automatically by minimod.PL from the contents
# of miniperlmain.c. Don't edit this file!

#       ANY CHANGES MADE HERE WILL BE LOST!
