This is the following in my ~/.gitconfig:

[url "git+ssh://vorlon@git.launchpad.net/"]
        insteadof = lp:

This configuration is described here:

  https://help.launchpad.net/Code/Git

We should probably make sure it gets into some Ubuntu documentation and not
just Launchpad documentation.

I feel this aligns with Bryce's comments about this being more of a
'submission' workflow.  It is an important distinction that none of the
other 'build' tools I mentioned involve pushing to a public repo.  That's
otherwise only done by 'bzr push', 'git push', 'dgit push', 'dput'.

Would 'git ubuntu push' or 'git ubuntu submit' be a better name for this
than 'git ubuntu build'?

Any objections to this being under a --verbose flag?
