I looked at those, and had to do a double-take with the
second one.

Calling "file" is "cheating". ;)  You can get crafty with
a lookup table and stat(2).

I mention this mainly because if Laughing Boy was
capable of reading your article, he'll surely launch
into a cackling fit that might brake his brane.  (That
is...if he understood the program, which he probably wouldn't.)

(Regarding article lookups and such, I use a shell script that calls
openssl(1) s_client to connect, log in, and leaves me with
the NNTP prompt...a place at which Feeb would be lost.)
