Migrating from SVN to Mercurial

[yvolk]

Matthias Jordan recently proposed migration of the AndTweet repository
from SVN to Mercurial.
This topic is for discussion of whether/when/how to migrate...

Some useful Links:
1) MercurialFAQ:

3) Google Code and Mercurial Tutorial for Eclipse Users - very brief,
but with video and links:

4) Google announcement of Mercurial support on Google Code:

My opinion is that we should go for Mercurial, the main question is
how to do this with minimum risks/resources...
