- #!/usr/bin/env 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!
