Charles, everything has been checked-in. The full set of features is available in SVN 90, or 2006-11-01: http://sipp.sourceforge.net/snapshots/sipp.2006-11-01.tar.gz
I would encourage everyone interested to check that their current set of features is working, as the changes are quite extensive (I did some testing, went through the code and couldn't come up with something bad). No documentation for now, but I'll used what you gave to provide it in the following days. Thanks a lot! Olivier.
