Commit 7b4a16e2c8869ba18264d0c44996880c8f9bb095
2011-03-28T13:59:48
Add git_tag_create_frombuffer API Expose the tag parsing capabilities already present in the library. Exporting this function makes it possible to implement the mktag command without duplicating this functionality. Signed-off-by: Carlos Martín Nieto <cmn@elego.de>
