Author: gunnar

Update of /kolabrepository/server/make-helper
In directory doto:/tmp/cvs-serv4777

Added Files:
	hg-patch-queue.mk 
Log Message:
Add a makefile definition for managing a patch queue with hg.

--- NEW FILE: hg-patch-queue.mk ---
# This is a very rough draft for updating a patch series using
# mercurial queues. The Makefile could see some optimizations but for
# the occasional upstream update it hopefully does fine.
