TC4 base dir

[Rob S.]

In TC3, you can change the base dir in server.xml, so that a new set of /logs, 
/webapps, and /work would be created and used somewhere else.  In TC4, all I see is 
the appBase attribute for each <Host>.  As well, there aren't any command-line params 
that I noticed in the startup class aside from -config.

Can I assume that no apparent way to set it and no command-line param means that it's 
not configurable?

I'm cool with that, I'm just writing some docs for us right now and want to be 
thorough!
