Fortunately, another reader of this list has written the
necessary parsers already and sent me a copy of the code via
e-mail; so the file-upload problem is solved for now. I've
essentially replaced Network.CGI with his code in my

Yes, the Network.CGI library is particularly weird in that
regard. The 'wrapper' API comes with several rather severe
limitations: the hard-coded list of supported 'cgiVarNames',
for example. I've also wondered why 'abort' isn't exported,
and so on ...
