Os: right now mod_aolsever (which has been renamed to mod_nsd in
the mean time :) will not boot ACS4.x (haven't tried OpenACS 4.x
yet) because of missing modules (nscache, nssha1, etc) and probably
also other bugs. I'm working on a quick and dirty emulation on Tcl
so people can use it if they have to, then I will do the proper
thing in C (probably when porting to Apache 2.0).
