//===-- Support/DotGraphTraits.h - Customize .dot output -------*- C++ -*--===//
//
// This file defines a template class that can be used to customize dot output
// graphs generated by the GraphWriter.h file. The default implementation of
// this file will produce a simple, but not very polished graph. By
// specializing this template, lots of customization opportunities are possible.
