[09] CAN I HAVE SEPARATE WEB DIRECTORIES FOR MY SUBDOMAINS?

     Yes!  When you run the 'mkvhost' command only the web directory for
     domain is created in $HOME/html/yourdomain.com.  Requests for 
     yourdomain.com and www.yourdomain.com are served out of that directory.

     If you'd like to enable VHOST for subdomain.yourdomain.com then just
     simple create the directory $HOME/html/subdomain.yourdomain.com and
     put your content there. 

     Each subdomain VHOST has a separate log file from the main VHOST
     domain.  Quotas are aggregated across all log files.
