This is 4va, the 4th dimensional graphics viewer for X-Windows. Please see the man page "4va.man" for details (to format it, use the command "nroff -man 4va.man | ul"). All you gotta go is unpack the tar file and issue "make". It should work, it's very simple. It even works on Linux. :) Please send any questions or bugs to mdw1@crux2.cit.cornell.edu. Share and Enjoy! Matt Welsh
