-# Maintainer's Notes:

-# Minor updates:
-#  1. Edit ./fetchsrcs.sh to point to the updated URL.
-#  2. Run ./fetchsrcs.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. Be sure to check if
-#  any new components have been added and package them as necessary.
