# Your file can define GIT_DIR, e.g.:

# Make sure GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL are also set
# or your rpm changelogs will look like crap.
# For each branch it can define a variable branch-BRANCH or tag-BRANCH
# giving the parent of BRANCH to diff against in a separate patch.  If
# the parent is unknown, it will use $(branch-upstream) defaulting to
# "refs/remotes/upstream/master".
# Defining tag-BRANCH means the tag corresponds to an upstream patch in
# the sources file, so that is used instead of generating a patch with
# git.  If there is no tag-upstream defined, it will figure out a vNNN
# tag or vNNN-gitN pseudo-tag from the last patch in the sources file.
# For example:
#	tag-some-hacks = v2.6.21-rc5
#	branch-more-hacks = some-hacks
# Leads to patches:
#	git diff v2.6.21-rc5..more-hacks > linux-2.6.21-rc5-some-hacks.patch
#	git diff some-hacks..more-hacks > linux-2.6.21-rc5-more-hacks.patch
# Whereas having no at all but doing
# "make GIT_DIR=... git/mybranch/test-srpm" does:
#	id=`cat` # auto-fetched via upstream file
#	git diff $id..upstream > linux-2.6.21-rc5-git4-upstream.patch
#	git diff upstream..mybranch > linux-2.6.21-rc5-git4-mybranch.patch
