# cdat-lite versioning is complicated as it is a repackage of
# cdat-cdunifpp.  There are therefore 3 version numbers to consider:
# CDAT, cdunifpp and cdat-lite.  If CDAT is on an unstable version
# that doesn't mean that cdms2 is unstable, therefore it is
# missleading to base the cdat-lite verison directly on the CDAT
# version.  Therefore we do the following:
#
#  1. cdat-lite distributions are versioned independently of CDAT and cdunifpp 
#  2. Other version numbers are described in the PKG_INFO description.
