<a name="line-4"></a>   Module      : Data.GraphViz.Parsing
<a name="line-5"></a>   Description : Helper functions for Parsing.
<a name="line-6"></a>   Copyright   : (c) Matthew Sackman, Ivan Lazar Miljenovic

<a name="line-8"></a>   Maintainer  : Ivan.Miljenovic@gmail.com
<a name="line-9"></a>
<a name="line-10"></a>   This module defines simple helper functions for use with
<a name="line-11"></a>   "Text.ParserCombinators.Poly.Lazy".
<a name="line-12"></a>
<a name="line-13"></a>   Note that the 'ParseDot' instances for 'Bool', etc. match those
<a name="line-14"></a>   specified for use with Graphviz (e.g. non-zero integers are
<a name="line-15"></a>   equivalent to 'True').
<a name="line-16"></a>
<a name="line-17"></a>   You should not be using this module; rather, it is here for
<a name="line-18"></a>   informative/documentative reasons.  If you want to parse a
<a name="line-19"></a>   @'Data.GraphViz.Types.DotRepr'@, you should use
<a name="line-20"></a>   @'Data.GraphViz.Types.parseDotGraph'@ rather than its 'ParseDot'
<a name="line-21"></a>   instance.
