IRC Definition Files

These files note interesting and useful information about IRC software. They are designed for IRC software developers, not regular IRC users.

A number of these files are based on the original lists from alien.net.au and are being updated and corrected to account for new software and versions.

The source code for this site is available on GitHub, under ircdocs/irc-defs. Pull requests to correct or update these lists are welcomed.
You can also talk to us at #ircdocs on freenode.
