| # 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! |
