Neither am I, so I've forwarded your comments to the person doing the XML work.

Well, it was done first with awk (that's what FreshPorts uses now) and 
now with perl (that's what it will use when the XML goes live).

Thanks.  That should be easily catered for.  These files are only 
referenced during the import of the XML.  And each XML dataset 
identifies the operating system from which it came.

Hmmm, that may be a sticking point.  FreshPorts assumes it can grab 
the updated failes as soon as the commit message arrives.

Why would anoncvs be best?  At present, when a commmit message is 
received, the code does a fetch and grabs 
the latest file as needed.  This doesn't happen for every commit (only 
those which involve the three files mentioned above).

Thanks.  I'm sure that the code for the FreeBSD => XML interface can 
be released as a starting point.

That's not necessary for FreshPorts.  We have included more in the 
DTD than is actually necessary.

You have been helpful already.  thanks.
