Please note that a notable part already made it into C in v2.12.1. There are still a few loose ends to tie, of course; it still makes for a great head start on your project, methinks.

Sure, you can make it an optional task, and I would be very happy if you followed up on it even after GSoC!

As far as the Perl dependency is concerned, I actually think there is only one serious one left: git add -i.

Granted, there is send-email, but it really does not matter all that much these days *except* if you want to use Git to contribute to projects that still use a mailing list-based patch submission process (the ones that come to mind are: Git, Linux and Cygwin). Most Git users actually do not submit any patches to mailing lists, therefore I tend to ignore this one.

The rest of the Perl scripts interacts with foreign SCMs (archimport, cvsexportcommit, cvsimport, cvsserver, and svn). I *guess* that it would be nice to follow up on the remote-svn work (which has not really gone anywhere so far, AFAICT the main driving contributor pursues different projects these days), but IMHO none of these are really needed to run Git.

Ciao, Johannes
