# 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.
