Usage: pisg.pl [-c channel] [-l logfile] [-o outputfile] [-m
maintainer]  [-f format] [-n network] [-d logdir] [-a aliasfile]
[-i ignorefile] [-h]

-ch --channel=xxx      : Set channel name
-l --logfile=xxx       : Log file to parse
-o --outfile=xxx       : Name of html file to create
-m --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
-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

As always, all options may also be defined by editing the source and calling
pisg without arguments.
