I did it for the communities of practice work but it has
not been integrated with the mainstream install yet.
see
http://cvs.openacs.org/cvs/*checkout*/openacs-4/contrib/packages/cop-base/lib/install.xml?content-type=text%2Fplain&rev=1.6
and
http://cvs.openacs.org/cvs/*checkout*/openacs-4/contrib/packages/cop-base/tcl/cop-procs.tcl?content-type=text%2Fplain&rev=1.6
(in particular cop::install)
I intend to move this to the right place in the toolkit but
I have not figured out where that should be yet.
