I have re-read my responses and you are absolutely correct.  Heck, even
if you weren't correct I should have been more civil.  Please forgive

That makes sense.  I have certainly experimented with enough
pathologically bad bzr workflows.  Using the right workflow can make a
big difference, and I would be the first to admit that the "proper" bzr
workflow might not be readily apparent.

You are welcome.

Fah, like I said, I re-read my posts.  You are being generous here.

I think it goes without saying that git fans are unlikely to ever think
too highly of bzr.  Once you have learned how to use git effectively
everything else is a step down.  The bzr or hg devs probably have some
arguments to the contrary, but generally speaking git's weakness is that
it is hard to learn to use.

Personally, I think that git's insistence on colocated branches is a
large part of what makes it hard to learn.  Learning to juggle branches
in git certainly confused the heck out of me.  It is somewhat ironic to
me that I have come full-circle and I now tend to do my work in a
lightweight checkout that I point at the right branch with bzr switch.
In at least one project that workspace isn't even inside the repository.
My workspace is at ~/project-name and my repository full of branches is
tucked away at ~/repos/project-name/branches .

A fancy aliasing plugin for bzr that automatically mapped commands like
"bzr switch foo" to "bzr switch $HIDDENREPO/project-name/foo" would get
me even closer to approximating git's colocated branches.  The truly
scary thing (to me anyway) is that I now can see *why* git has the UI
that it does.

Now that I have learned to use bzr, I could probably wrap my head around
git :).
