NAME
     gvcolor - flow colors through a ranked digraph
     ( previously known as colorize )

SYNOPSIS
     gvcolor [ files ]

USAGE
     dot file.gv | gvcolor | dot -T<format>

DESCRIPTION
     gvcolor  is a filter that sets node colors from initial seed
     values.  Colors flow along edges from tail to head, and  are
     averaged  (as HSB vectors) at nodes.  The graph must already
     have been processed by dot.  Appropriate choice  of  initial
     colors  yields  drawings in which node colors help to empha-
     size logical relationships between nodes, even when they are
     spread far apart in the layout.

     Initial  colors  must  be  set  externally,  using the color
     attribute of a node.  It is often effective to assign colors
     to  a  few  key source or sink nodes, manually setting their
     colors by editing the graph file.  Color  names  are  as  in
     dot(1): symbolic names or RGB triples.  It is best to choose
     some easily-distinguished but related colors; not  necessar-
     ily  spaced  evenly  around  the  color wheel.  For example,
     blue_green, green, and light_yellow looks better  than  red,
     green, blue.

     Certain  graph  attributes  control  the  gvcolor algorithm.
     flow=back reverses the flow of colors from heads  to  tails.
     saturation=.1,.9  (or  any  two  numbers  between  0  and 1)
     adjusts the color saturation linearly from least to greatest
     rank.   If  Defcolor  is set, this color value is applied to
     any node not otherwise colored.

EXIT STATUS
     The following exit values are returned:

     0   Successful completion.

     1   If  nodes  of  the  graph  do  not  possess  a   ``pos''
         attribute.

BUGS
     It would be nice to make the program work without relying on
     an initial pass through dot.
