#
# This script will update all the modules listed below so that
# common points to master in the common module.
#
# If you have many of the GStreamer modules checked out in a particular
# directory, it's best to run this script from that directory. For
# example, I check everything out in ~/gst, so this file is
# ~/gst/common/update-common. To do an update, I do
# 'cd ~/gst ; ./common/update-common'. This will automatically use
# the refs in your existing checkout when cloning the temporary
# checkout. Alternatively, you can use the reference variable below.
#
# Options:
#
# --dry-run : pass --dry-run to git push, don't actually push the changes
# --keep : keep temporary checkouts around instead of deleting them
# Set this variable to point to any directory containing existing
# git # checkouts, and git will pull objects from there, decreasing
# network usage.
