# Create a new set of clone channels from the RHEL base channel
# This will be used to easily cut a point-in-time "major" release
# for the $RELNAME builds, then subsequent "point" releases can be created
# as clones-of-clones+errata using clone_release_from_existing.sh
#
# We take an optional argument which specifies RHEL version to clone from
if [ $# -eq 1 ]

# clone-channel name, convention is to be ${RELNAME}_5_1.0, where RHEL5 is being cloned for

# Cutting clone-of-clone "point" releases will increment 1.1->1.1 etc
