-n --network=xxx       : IRC Network this channel is on.
-d --dir=xxx           : Analyze all files in this dir. Ignores logfile.
-p --prefix=xxx        : Analyse only files starting with xxx in dir.

-co --configfile=xxx   : Config file
-h --help              : Output this message and exit (-? also works).

Example:

 \$ pisg.pl -n IRCnet -f xchat -o suid.html -ch \\#channel -l logfile.log
