[Python-3000] Invitation to try out open source code review tool

Some of you may have seen a video recorded in November 2006 where I
showed off Mondrian, a code review tool that I was developing for
Google (http://www.youtube.com/watch?v=sMql3Di4Kgc). I've always hoped
that I could release Mondrian as open source, but it was not to be:
due to its popularity inside Google, it became more and more tied to
proprietary Google infrastructure like Bigtable, and it remained
limited to Perforce, the commercial revision control system most used
at Google.

What I'm announcing now is the next best thing: an code review tool
for use with Subversion, inspired by Mondrian and (soon to be)
released as open source. Some of the code is even directly derived
from Mondrian. Most of the code is new though, written using Django
and running on Google App Engine.

I'm inviting the Python developer community to try out the tool on the
web for code reviews. I've added a few code reviews already, but I'm
hoping that more developers will upload at least one patch for review
and invite a reviewer to try it out.

To try it out, go here:


Please use the Help link in the top right to read more on how to use
the app. Please sign in using your Google Account (either a Gmail
address or a non-Gmail address registered with Google) to interact
more with the app (you need to be signed in to create new issues and
to add comments to existing issues).

Don't hesitate to drop me a note with feedback -- note though that
there are a few known issues listed at the end of the Help page. The
Help page is really a wiki, so feel free to improve it!
