[rupert THURNER]

mercurial has mq for managing patches, and it is suggested that git
should not need a dedicated tool any more:

> Since we have automatic git integration in GAR builds, writing patches

> there's no easy way to update a patch. We either need to create
> layered patches, or manually remove the patch, apply it off-gar,
> modify, and then re-create it.

> There is a piece of software which can maintain a mapping between
> patch files and upstream source files. It's called Quilt.

> Generally, the interaction with quilt goes like this:
>
> 1. Create me a new patch placeholder, called foo (quilt new foo)
> 2. Patch foo will modify file src/bar.c (quilt add src/bar.c)
> 3. Edit the file
> 4. Update the patch with my modifications (quilt refresh)
> 5. Record my comments on the patch (quilt header -e)
>
> When you want to modify a patch, you go edit the sources again, and
> call quilt refresh. Quilt stores its own state in a directory called
> ".pc".
>
> Does anyone else have experience with quilt?
