initial commit

currently supports:
	auto-patch
	add overlay to eix index
	show diff to old eix index on emerge --sync

Add this to your make.conf:
	# portage autopatch
	PATCH_OVERLAY="/var/lib/portage/patches"

	# portage overlays
	source /etc/portage/overlays/make.conf

and create configs for the overlays in /etc/portage/overlays.
Currently the only supported options are LOCATION and
CACHE_FORMAT (for eix) in bash syntax like:
	LOCATION="/var/portage/repositories/proaudio"
	CACHE_FORMAT="parse*"

or something like this. If CACHE_FORMAT is missing the default
of eix is used.

For autopatch you have to put the patches in the subdir:
	${PATCH_OVERLAY}/CATEGORY/PACKAGE/

All files in that directory with .patch extension are applied
during ebuild execution.
