Rhapsody is a text console IRC client for Unix operating systems. It is small, fast, portable and easy to use, yet it is full featured. The thing that separates it from the crowd is its intuitive menu driven user interface. Check out the screenshot area for more information.
It is written entirely from scratch in C and uses the ncurses library. It compiles and has been tested on Linux, FreeBSD, OpenBSD, NetBSD, Solaris, IRIX, HP-UX, Tru64, Mac OS X, BeOS, Hurd, Syllable and Cygwin.
Most importantly, Rhapsody is FREE software, released under the GPL license. Grab it from the download section!
