Subject: [PATCH] Added --add-version option. This allows you to add an
 implementation to an existing interface without having a local file. The new
 implementation is added right after the last existing one in the file. To add
 an archive at the same time:

$ 0publish --add-version=1.2 --archive-url=http://site/prog-1.2.tgz iface.xml
