The X11 version is available via HTML as source code. It has been successfully used with both Linux and FreeBSD.

To build it from source, you will need GreenCard 3.01 and GHC 6.x as well.

The latest release doesn't yet work with Win32. In the meantime, you can use the previous version (2.0.5).To use it, simply download and run the installer.
