# Usage:
# update-contribs.sh
#
# update the list of all contribs.
#
# This does the following
# - run svn up to get the updates of all the scripts and latest contrib list
# - updates the local list of contribs:
# . For the first checkout, the list of contribs will be copied in
# a contribs.local
# . for future checkouts, checks all potential updates and ask you
# what to do in case of doubt
# - for all the contribs that have to be updated, check that there is
# no modification in their svn
# - update all the contribs that need to be updated
# parse some command line options of the form
# update-contribs.sh -<option>
#
# supported options at the moment are
# -h show a help message
# --force assume the answer to every question is "yes"
