#!/usr/bin/perl
# a script for use by autoconf to make the Makefiles
# from the Makefile.in's
#
# the original autoconf mechanism first splits all substitutions into groups
# of ca. 90, and than invokes sed for _every_ Makefile.in and every group
# (so around 2-3 times per Makefile.in). So this takes forever, as sed
# has to recompile the regexps every time.
#
# this script does better. It changes all Makefile.ins in one process.
# in kdelibs the time for building Makefile went down from 2:59 min to 13 sec!
