# This is a script to output the value for the %{dist}
# tag. The dist tag takes the following format: .$type$num
# Where $type is one of: el, fc, rh
# (for RHEL, Fedora Core, and RHL, respectively)
# And $num is the version number of the distribution.
# NOTE: We can't detect Rawhide or Fedora Test builds properly.
# If we successfully detect the version number, we output the
# dist tag. Otherwise, we exit with no output.
