"source" is fine, it could also be "demos".
Just a thought: Could the HTML files that are displayed also show their
last changed SVN revision? That way automated tests could raise a
warning if they are dealing with pages they were not recorded against.
It should be in an easily locatable place, like the beginning or the end
of the doc with a distinct ID or class name, like "svnRevision".
I could hack that up once I have SVN access. Just need a yay or nay.
Cheers!
