On a meta-issue, should we be editing the results and ideas into a file 
in SVN, or plan to review these threads later?

I hope we can end up with full, well-tested instructions for a few 
different environments.

Actually SVN, not CVS, but same principle.

A readme file should assume the user reads it at the first point at 
which the readme becomes accessible, no earlier. Is the readme going to 
be inside the .tgz, or outside it? What is a .tgz?

For Windows, it is Tools -> Option ->Java -> Maven

Did that, followed by the "install" and "site" goals. There were several 
warnings. Would you like the console output, or are they expected?

“Getting started” page.

Yes, I see the end point of this exercise as a much better "Getting 
started" page.
