initial version for Ubuntu Server 12.04
Notes and instructions provided here are for fresh installations of Ubuntu Server 12.04 on a
VMware virtual machine. Responses from and requirements for computers with these
applications already installed, or with legacy versions of these applications, may be different

Final disclaimer: These instructions are an amalgamation of what worked. I did not get
everything to work, then retest the instructions from scratch. These instructions are believed to
be correct and complete. Other than that, good luck.
