   You almost definitely do /not/ want to use this module.  It is only
   defined for completeness when parsing existing Dot code.

   Graphviz contains a list of colors known as the /Brewer color
   schemes/.

   These colors are available under an Apache-style license:
   <http://www.graphviz.org/doc/info/colors.html#brewer_license>.  As
   such, they are not recommended for general use, and have only been
   included in this package for completeness.

   The complete list of Brewer colors can be found at
   <http://www.graphviz.org/doc/info/colors.html#brewer>.
