 .SH DESCRIPTION
 These are a collection of programs for drawing graphs. 
 There is actually only one main program; the specific layout algorithms
 implemented as plugins. Thus, they largely share all of the same command-line 
 options.

 draws directed graphs.  It works well on DAGs and other graphs
 that can be drawn as hierarchies.

 and IEEE TCVG Symp. on Visualization, 2000, pp. 33-42). The clusters of the graph are used to
 specify the tree.

+draws the graph using its cluster structure. For a given cluster, each of its subclusters is laid out internally. 
+Then the subclusters, plus any remaining nodes, are repositioned based on the cluster's \fBpack\fP and \fBpackmode\fP
+attributes.
