getting oriented questions
**dual 2.5 PM G5 running Tiger (10.4.2)**

I'm just getting into rdiff-backup so if these questions are to simple 
please just point me in the right direction :-)

I'm working on an ongoing (wip) article <a 
href="http://homepage.mac.com/lee_cullens/Bx3.html";>Backup::Restore</a> 
that includes native tool usage examples.  I was just getting into some 
of the more "elaborate" uses of Tiger's new rsync (which isn't quite 
ready for prime time yet) and in looking around for various uses came 
across rdiff-backup.  I think including a good open source tool would be 
appropriate and took the easy out of installing it from DarwinPorts 
which included the dependency librsync.  

I also dabble a little in Python and have Bob's 2.4.1 pythonmac installed.

So with that understood, I am interested in ACL and EA support.  

First, for EA support I have installed "xattr" (pythonmac package) which 
is to Mac OS X what pyxattr is to Linux (though I don't think the 
implementations are quite compatible).  Will rdiff-backup recognize 
"xattr" and preserve user-level Extended Attributes?  

Second, for ACL support I don't seem to have anything called "pylibacl" 
on my system and can't find it in the Mac specific packages.  Is this 
Mac compatible and if so where might be the best place to find it (for 
someone not accustomed to building things on Mac and Unix)?

Thank you,
