# Usage: daorig

# Fake up an "original" source tarball for a Debathena package.  Run
# this from the top level of a checkout or copy of the sources for a
# Debathena package; the orig tarball will be created in the parent
# directory if necessary.

# If the package has no Debian version component, this script will do
# nothing.  If an orig file already exists, this script will also do
# nothing.
