The PackageIndex.find_links(url_list) method will give it specific 
URLs; these can be any HTML web page, as long as they contain links 
to directly-downloadable eggs or other easy_install-able distribution 
formats.  It can also be given a host mask to restrict what hosts it 
will attempt to connect to (either to read HTML or download other files).

The PackageIndex class can be subclassed to replace its 'open_url' 
method, if desired.
