Name:       opendaylight
Version:    4.1.0
# The Fedora/CentOS packaging guidelines *require* the use of a disttag. ODL's
#   RPM build doesn't do anything Fedora/CentOS specific, so the disttag is
#   unnecessary and unused in our case, but both the docs and the pros (apevec)
#   agree that we should include it.
# See: https://fedoraproject.org/wiki/Packaging:DistTag
