 # Set up a temporary schemas/ directory containing only some of the full set of
 # pacemaker schema files.  This lets us know exactly how many schemas are present,
 # allowing us to write tests without having to make changes when new schemas are
 # added.
 #
 # This directory contains the following:
 #
 # * pacemaker-next.rng   - Used to verify that this sorts before all versions
 # * upgrade-*.xsl        - Required by various schema versions
 # * pacemaker-[0-9]*.rng - We're only pulling in 15 schemas, which is enough
 #                          to get everything through pacemaker-3.0.rng.  This
 #                          includes 2.10, needed so we can check that versions
 #                          are compared as numbers instead of strings.
 # * other RNG files      - This catches everything except the pacemaker-*rng
 #                          files.  These files are included by the top-level
 #                          pacemaker-*rng files, so we need them for tests.
 #                          This will glob more than we need, but the extra ones
 #                          won't get in the way.
