I'm still trying to figure out (1) which variables I need and (2) how I
would get the POST data through. This seems very messy.

I think I prefer this approach as well - ie instead of doing "open LOG,
$logfile" I need to open a pipe from a command, right?

But I'm having trouble getting this to work as well.  I have written a
little script catmaillog (which obviously chooses the correct log and
cats it), and I can "sudo catmaillog" from the command line as www-data
and it works correctly. But when I run myscript.pl, either from the
command line or via Apache, I get "cannot open: Permission denied".

Oh well, at least it's a little more Perl-relevant now...
