=for usage
Usage:    ssh git@host readme <repo>
          ssh git@host readme <repo> rm
          cat <filename> | ssh git@host readme <repo> set

Show, remove or set the README.html file for repo.

You need to have write access to the repo and the 'writer-is-owner' option
must be set for the repo, or it must be a user-created ('wild') repo and you
must be the owner.

The WRITER_CAN_UPDATE_README option is gone now; it applies to all the repos
in the system.  Much better to add 'option writer-is-owner = 1' to repos or
repo groups that you want this to apply to.

This option is meant to cover desc, readme, and any other repo-specific text
file, so it's also a blunt instrument, though in a different dimension :-)
