Done.

By the way, some fields return "none."  Should it be converted to #f?

FSF's shop.

I think so.

I'm using 2.0.7; 'http-get' returns a string.  I used the following:

+             ((string<=? (version) "2.0.7")
+              (open-input-string data))
+             (else data)))

Done.

I'll ask Karl about this.
