# Procedure to do first time:
#  cd ~/release
#  git clone ... coccinelle
#  cd coccinelle
#
# Procedure to do each time:
#
#  1) make prerelease # WARN: These will clean your local rep. of pending modifications
#
#  UPDATE VERSION number in ./version
#  and commit it with
#
#  2) make release
#
#  The project is then automatically licensified.
#
#  3) make package
#
#  if WEBSITE is set properly, you can also run 'make website'
# Check that run an ocaml in /usr/bin

# The 'git rebase' is in there just in case you started with
# unpushed changes. However, that is probably something you should
# not do in the first place.
