# A longish note on versions because I will forget:
# This ebuild fetches tarballs from github instead of using cros-workon
# because having a system-level package using git clone to fetch sources
# adds new ways for bootstrapping to fail. Also ${PN} needs to have a
# one-to-one relationship with git commits to make mirroring/caching work.
# - The version field is the date of the last upstream commit.
# - Use patch (_p) instead of revision (-r) when updating the git hash.
# So: 20130722_p1 includes upstream up through July with one CoreOS patch.
