Cool!

Ok, I pointed hggit = at my hg-git binary. I'm guessing that was the  
wrong thing to do.

What is a bookmark? I never understood that part...

If you hg update and then re-push it updates the repo? (I've done one  
commit today, small bugfix for -- option parsing.)

Hmm, I wonder if the conversion and hash generation is deterministic?  
(If two people convert the repository into separate git repos and one  
pulls from the other, it figures out which changes it already has? Or  
do they have to pull from clones of the same converted git repo?)

You got farther than I did, but I tend to ask the wrong questions and  
break stuff. (In this case, trying to actually put something after the  
= in the rc file because I asked "what should go there"...)

It's coming up on 1am, but I'll try this in the morning and see if I  
can actually put something in the old https://github.com/landley/toybox  
directory. :)

Thanks,
