If that fails it falls back to the author +specified with --author. If the --author flag was not given +the patch description is displayed and the user is asked to +interactively enter the author of the patch. + +If a subject is not found in the patch description the patch name is +preserved as the 1 line subject in the git description. + +OPTIONS +------- +--dry-run:: + Walk through the patches in the series and warn + if we cannot find all of the necessary information to commit + a patch.
