/* Naming conventions:

JK_CONF_DIR == serverRoot/work  ( XXX /jkConfig ? )

- Each vhost has a sub-dir named after the canonycal name

- For each webapp in a vhost, there is a separate WEBAPP_NAME.jkmap

- In httpd.conf ( or equivalent servers ), in each virtual host you
should "Include JK_CONF_DIR/VHOST/jk_apache.conf". The config
file will contain the Alias declarations and other rules required
for apache operation. Same for other servers. 

- WebXml2Jk will be invoked by a config tool or automatically for each
webapp - it'll generate the WEBAPP.jkmap files and config fragments.

WebXml2Jk will _not_ generate anything else but mappings.
It should _not_ try to guess locations or anything else - that's
another components' job.
