More bzr hacking

I've extended bzr-establish to give it a new command: hack.

'bzr hack lp:foo' will create a repository with working trees called 'foo' and fetch the lp:foo branch into that repository.
'bzr hack --repository ~/repos lp:foo' will create a repository in '~/repos/foo', a working tree area in 'foo', fetch the branch into the repo and make a light-weight checkout in the working tree area.

You can also specify a non-Launchpad branch, e.g. 'bzr hack http://example.com/some/branch/trunk foo'. This will make a repository called 'foo', put the branch in there and... well, you get the picture.

The plugin lives at lp:~jml/+junk/bzr-establish. It's buggy, not particularly well tested and rough as guts. Still, it's worth a play.
