Subject: EAPI 5: User patches (no-op dummy stub for now)
X-Git-Tag: v2.2.0_alpha124~30
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=6b4b621f1abcf21d3bfa54b323126a3ef11eb52c;p=portage.git

EAPI 5: User patches (no-op dummy stub for now)

A real apply_user_patches implementation will be a bit more work, so
for now we'll just implement the minimum amount necessary to satisfy
the spec:
