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://anongit.gentoo.org/proj/emacs-tools.git https://anongit.gentoo.org/git/proj/emacs-tools.git git+ssh://git@git.gentoo.org/proj/emacs-tools.git https://gitweb.gentoo.org/proj/emacs-tools.git/ Patch naming follows this convention: __.patch The is used for consistent patch ordering. The 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.)
