I just wrote a small openacs package for my personal convenience that
acts as webinterface to tclwebtest, which uses a very evil hack to
make the tclwebtest procs available within aolserver: it calls
'source' fot the tclwebtest libraries every time before they are
needed. Actually it was planned to only source if necessary, saving
some time when it has been sourced for the current thread already. I
attached that proc that does that below. No idea why the on-demand
sourcing is deactivated (see the delete namespace call after TODO).

Ideally I would like to make it available via package require, but
that doesn't work with the older aolserver versions (at least not
3.3ad13). It's propably an option with aolserver 4.


hope that helps, til
