  create the release tars from a SVN candidate. The candidate is expected
  to be found in SVN at 'tags/$version-candidate', as prepared by the
  'make-candidate.sh' script.
  If no version is given, the current version in the checkout is used.
  Arguments:
    version        as 'm.n.p(-suffix)?', the version to use.
  Options:
    -h             print usage information
    -s sign-user   use gpg/pgp key from 'sign-user'
EOF
  exit 1
