Well, please bear with bzr for the moment, if it comes out to be not 
feasible, we will switch back to svn. For eclipse, go 
https://launchpad.net/bzr-eclipse (never tried this plugin and never used 
(not even seen, for that matter) eclipse, though).

It applies to core as well (perhaps primarily). If you will refactor 
containers, I will not be very happy if trunk will be not compile for some 
weeks, since that will break what I will do - e.g. messing with Body stuff, 
which will break others; work.

I found bzr IRC to be very helpful, though. Some remarks to that:

1. The checkout speed is related to many roundtrips for both http (better) 
and sftp (worse). Next month, launchpad will add support for bzr+ssh and 
bzr+http, which should remedy these problems.

2. You can do "bzr status -r 
-1:https://code.launchpad.net/~yade-team/yade/trunk"; for status against 
latest (-1) upstream revision. I wrote a plugin to simplify that -- put it 
into ~/.bazaar/plugins and say just "bzr st -r master:" or "bzr diff -r 
master:" (attached).

3. Tags are disabled by default for backwards compatibility with bzr <0.15. 
It is a matter of running "bzr upgrade --dirstate-tags" in the repo, then it 
will work. If it is needed, we can upgrade the central repo.
