[Lunar-commits] r24966 - lunar/trunk/var/lib/lunar/plugins

[Stefan Wold]

Author: ratler
Date: 2007-06-21 22:59:01 +0200 (Thu, 21 Jun 2007)
New Revision: 24966

Added:
   lunar/trunk/var/lib/lunar/plugins/build-zpatches.plugin
Log:
New plugin to allow autopatching of sources without editing a module.
Create $MOONBASE/zlocal/_patches/$MODULE and drop your p1 or p0 patch in
that directory. $MOONBASE/zlocal/_patches/$MODULE/$VERSION is also valid
if a patch is only to be applied to a certain version.

If patch order is neccesary just prefix each patch with 01, 02 etc.
