  Gviz is a tool for generating graphviz dot data with simple Ruby's syntax.
  It works with a graph spec file (defaulting to load 'graph.ru').

  Example of graph.ru:

    route :main => [:init, :parse, :cleanup, :printf]
    route :init => :make, :parse => :execute
    route :execute => [:make, :compare, :printf]

    save(:sample, :png)

  EOS
  puts banner
  help
end

#build(file = 'graph.ru') ⇒ Object
