#  and commit it with
#
#  2) make release

#  Remember to comment the -g -dtypes in this Makefile
#  You can also remove a few things, for instance I removed in this

#  make sure that ocaml is the distribution ocaml of /usr/bin, not ~pad/...
#
#  3) make package
#
#  if WEBSITE is set properly, you can also run 'make website'
# Check that run an ocaml in /usr/bin

# To test you can try compile and run spatch from different instances
# like my ~/coccinelle, ~/release/coccinelle, and the /tmp/coccinelle-0.X
# downloaded from the website.

# For 'make srctar' it must done from a clean
# repo such as ~/release/coccinelle. It must also be a repo where
# the scripts/licensify has been run at least once.
# For the 'make bintar' I can do it from my original repo.
