libstrophe looks interesting ... BUT

1. what's this scons thing? http://www.scons.org/ (make + automake replacement in python)
2. it won't build ... snapshot or git clone
git clone git://code.stanziq.com/libstrophe

Ahhh. No changes in a while (January) now a couple of recent changes:
http://code.stanziq.com/cgit/strophe/libstrophe/log/SConstruct "20 hours Removed SCons."
http://code.stanziq.com/cgit/strophe/libstrophe/log/src/ "Abstracted XML parser library and switched to autotools building."
http://groups.google.com/group/strophe-dev/

Hah ha ha.
I don't see any stable release available for download for libstrophe source.

This slightly older svn builds with scons

Oh well, let's leave this mess scattered over the floor.
