Re: [Jython-dev] GitHub Jython repo broken

[Jeff A. <ja...@fa...>]

I have made a valid (I think) git repo from hg by migrating it using 
https://github.com/frej/fast-export . It does not have the false root 
problem seen in the current official repo (or multiple heads per 
branch). It may not yet be attributing correctly to GitHub user names.

I will repeat this (so I can do it repeatably!) in such a way that I end 
up with a repo on my personal account, and check that it looks right 
from GitHub, both history and attribution. Then I'll see if I can make 
it appear at https://github.com/jython/jython, which is by no means certain.
