Thanks!  It might be good to have slightly more, though.

James, at some point could you look through the tutorial, and
maybe add a sentence somewhere mentioning systems?  I don't want
an actual definition (that's done in the Glossary), but just
something that would make a serious reader (unfamiliar with the
term) go "hmm... what does that mean?" and then look it up in the
glossary.

Use some of that famous understated English tact.  Or something
like that.  Don't be a Scot.  ;)

Cheers,
