Usage: pisg.pl [-ch channel] [-l logfile] [-o outputfile] [-ma maintainer]
[-f format] [-n network] [-d logdir] [-mo moduledir] [-s] [-h]

-ch --channel=xxx      : Set channel name
-l  --logfile=xxx      : Log file to parse
-o  --outfile=xxx      : Name of html file to create
-ma --maintainer=xxx   : Channel/statistics maintainer
-f  --format=xxx       : Logfile format [see FORMATS file]
-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.
                         Only works with --dir
-mo --moduledir=xxx    : Directory containing pisg's modules.
-co --configfile=xxx   : Config file
-s  --silent           : Suppress output (except error messages)
-h  --help             : Output this message and exit (-? also works).

Example:

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

All options may also be defined by editing the configuration file and
calling pisg without arguments.
