1. This is a program similar to xbiff with a nicer output This is a program similar to xbiff, except that it provides somewhat nicer output. It requires the Mesa (OpenGL clone) libraries to render the 3D mailbox. The idea comes from the "mailbox" program available on SGI machines, and hence tries to mimic some of the features present in it. Note that this is an alpha version, and hence there are still some outstanding bugs. From Debian 3.0r0 APT
