savIRC

savIRC is an Open Source IRC Client written in Tcl/Tk. It was created by Saverio Castellano.

savIRC has many features that the popular IRC clients have.

* Cross Platform, currently runs on Unix-like OS's and Windows (Mac is untested)
* Text Preview when using Color/Bold/Underline codes

* Multiple Network Connections
* Many more ...
