IRC client written entirely in Bash (no external binary calls)

A lot of people use bash scripts to setup their dev environments on new machines. I can think of several reasons why I would want an easy to install zero dependency irc client on a new machine.

Bash is hands down one of the most useful languages out there, it is nearly as ubiquitous as javascript.

For an example on how powerful bash can be I would take a look at Ben Alman's (Cowboy) dotfiles repo.

It's entertaining for the same reason code golf is entertaining. It's fun, educational, and clever.
