graphviz: Attempt to make the recipe an actual recipe

Runs into internal compiler error on gcc 2. Won't pursue this any
further.

-DESCRIPTION="graphviz - Open Source Graph Visualization Software."
+SUMMARY="Open Source Graph Visualization Software"
+DESCRIPTION="Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics,  software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.
+
+The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages, PDF or Postscript for inclusion in other documents; or display in an interactive graph browser. (Graphviz also supports GXL, an XML dialect.)  Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, rolland custom shapes."
