# Adapted from Porting/cmpVERSION.pl by Abigail
# Changes folded back into that by Nicholas
#
# If some modules fail this, you need a version bump (_001, etc.)
# AND you should probably also nudge the upstream maintainer for
# example by filing a bug, with a patch attached and linking to
# the core change.
#
# This test script works by finding the last non-RC tagged commit,
# which it assumes was the last release, then for each module:
# if it has changed since that commit, but its version number is still the
# same as that commit, report it.
#
# There's also a module exclusion list in Porting/cmpVERSION.pl.
