# Maintainer's Notes:
#
# Minor updates:
#  1. Edit ./manifest.sh to point to the updated URL. Upstream sometimes
#     releases updates that include only the changed packages; in this case,
#     multiple URLs can be provided and the results will be merged.
#  2. Run ./manifest.sh and ./dependencies.sh.
#  3. Build and enjoy.
#
# Major updates:
#  We prefer not to immediately overwrite older versions with major updates, so
#  make a copy of this directory first. After copying, be sure to delete ./tmp
#  if it exists. Then follow the minor update instructions.
