I have written a patch-application tool as part of the (otherwise stalled) ArcheoloGIT project, clonable from http://ydirson.free.fr/soft/git/argit.git/.

Side note: it could make sense to finalize this script and integrate it in git proper. Opinions ?

Although the command-line interface would probably benefit from an overhaul, it is fully functionning, notably supporting:

- application of several patches in one row
- application of non-incremental patches - eg. the 2.4.19rmk2 patch
applies to plain 2.4.19, not to 2.4.19rmk1

| $ ../argit/ag-import-patch --help
| Usage: ag-import-patch ( [-v] [-n] [-b BASE|-i] [-N NAME] [-p PARENT]... [-t TAG] PATCH )*

| Import a revision in a GIT history from a patch.

Since it lacks doc, here is it:

-i		- process subsequent paches as incremental (the default)
-b BASE		- process subsequent paches as applying to commit BASE
-N NAME 	- use given NAME instead of patch filename for generating
		  commit message (useful for /dev/stdin import)
-t TAG		- tag after import
-p PARENT	- add PARENT to the parents

eg:

$ git checkout v2.4.19
$ ag-import-patch -b v2.4.19 \
	-p v2.4.18rmk6 -t v2.4.19rmk1 patch-2.4.19rmk1.diff \
	-t v2.4.19rmk2 patch-2.4.19rmk2.diff

Hope this helps,
