xps--Dynamic Process Tree Watching Under X

The xps program dynamically displays the Unix processes as a tree or forest in an X Window, the roots on the left and the leaf processes (those with no children) on the right. The status of each process running, sleeping, stopped, etc., can be indicated by different colors. Different users can appear as different colors too.

Process selection can be made per user, all users, or through a regular-expression pattern.
