A converter and statistics utility for IRC log files.
Usage:
ilc parse <file>...
ilc convert <informat> <outformat> [--date DATE] [--tz SECS] [--channel CH]
ilc (-h | --help | -v | --version)
Options:
-h --help Show this screen.
-v --version Show the version (duh).
--date DATE Override the date for this log. ISO 8601, YYYY-MM-DD.
--tz SECONDS UTC offset in the direction of the western hemisphere. [default: 0]
--channel CH Set a channel for the given log.
