#!/bin/bash
#
# 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
#
# - build the list of contribs:
# . by default, these are read from 'contribs.svn'
# . local requests can be specified in 'contribs.local'
# (in which case they take precedence)
#
# - for all the contribs that have to be updated, check the currently
# installed version and, if it does not match the one in
# contribs.svn (or contribs.local), ask if the user wants to update
# them. If yes, update the installed version.
#
# 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"
