Rdfherd

We need separate documentation for RDFHerd.

There is some documentation mixed in with the "how to create a mirror" documentation here and here.

All rdfherd commands are run in the following format:

rdfherd   [args...]

Commands
I've found the following commands useful:

start stop bundle_update configure

Command: start
Starts the Virtuoso server. This can take a few seconds-to-minutes, so the log file (/virtuoso/install/virtuoso.log) should be checked with tail until a "Server started" message appears.

Command: stop
Shuts down the Virtuoso server.

Config.pl format
You need a class, a version number, and other things.
