 # This script will update all the modules listed below so that

+# 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.

 # Set this variable to point to any directory containing existing
 # git # checkouts, and git will pull objects from there, decreasing
-# network usage.  You can also run this script from that directory.
