Hi Glen,

I can add an extra description line; this is a good idea. We do require  
each mirror to use the same directory structure, but it can start at  
any point on their website. To illustrate this, here's a sample from  
the mirror script (if you're interested in seeing the whole script,  
just let me know):

// define the mirror sites and their descriptions
// sites must have an ending slash
$G_sites = array(	'http://download.blender.org/' 		=> 'Blender  
Foundation Site (Europe)',
				'ftp://ftp.cs.umn.edu/pub/blender.org/'	=> 'University of Minnesota  
(USA)',
				'http://planetmirror.com/pub/blender/'	=> 'Planet Mirror (USA)'
			);

Each mirrorsite has a different 'documentroot' for our files. Is that  
what you mean?

Cheers,

Bart
