Patchsets for some Emacs packages are too large for the Portage tree
and we therefore maintain them in a Git repository. From there, they
are bundled up into a tar archive that is distributed via the Gentoo
mirroring system. Specific information about the patches can usually
be found at the top of each patch.

The patches are kept in the "patchsets" branch of the repository at:
   git://git.overlays.gentoo.org/proj/emacs-tools.git
   http://git.overlays.gentoo.org/gitweb/?p=proj/emacs-tools.git

Patch naming follows this convention:
   <number>_<arch>_<description>.patch
The <number> is used for consistent patch ordering. The <arch> field
corresponds to the host architecture, or has a value of "all" if the
patch should be applied for everyone. (Using values other than "all"
is strongly discouraged.)
