Subject Re: what is apache? (Re: Small direction change for APR's file I/Oroutines.)

I'm forced to agree with Dean that a few of the modules would be better off
as OS specific.  Making them specific would be useful and would make
rewriting them into the 2.0 world easier, whilst giving a server that was
easier to tailor.  The windows port might gain by having a different set of
modules that each has it's own config directives.  Certainly platforms such
as OS2 and BeOS probably would, and this fits very nicely with my recent
proposal for configuration files!  (Sorry couldn't resist that :-))
