[galaxy-commits] commit/galaxy-central: greg: Add the ability to export a specified repository revision from the tool shed to a gzip compressed archive saved locally. The ability to import this archive to the same or another tool shed is not yet implemented, but coming soon. All of the repository's repository dependencies can optionally be exported into the same archive. The archive includes a manifest.xml file that contains the order in whcih the repositories in the archive must be imported.
