Graphviz to LaTeX converter

 The purpose of dot2tex is to give graphs generated by the graph layout tool
 Graphviz a more LaTeX friendly look and feel. This is accomplished by:
 .
  - Using native PSTricks and PGF/TikZ commands for drawing arrows,
    edges and nodes.
  - Typesetting labels with LaTeX, allowing mathematical notation.
  - Using backend specific styles to customize the output.
