Vamp Website Layout
-------------------

Most of the site is served through a small Spark Java application,
whose code is found in this repo.  The purpose of this application is
to serve the dynamically generated plugin download page, but for
convenience it is also configured to serve up the static HTML content
(found in the public/ subrepo) and static RDF data (rdf/ subrepo).

This means the Apache front-end server should be configured to pass
everything through to the Spark server on a local port, except for the
forum (PHP to be run by Apache) and the wiki (redirecting to the
SoundSoftware code site, we no longer host a wiki locally).

That is, these are handled by Spark as long as Apache passes / through
to it appropriately:

  /                Static content served through Spark
  /download.html   Dynamic content generated by Spark

But these need to be overridden by Apache before reaching Spark:

  /rdf             Static content served by Apache (plus index pages etc)
  /forum           Dynamic PHP content
  /wiki            Redirect
