     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>.
