  * This file contains code to output a description of tasks and their
  * dependencies in ".dot" format.  Prior to running, the user should run "pub
  * get" in the analyzer directory to ensure that a "packages" folder exists.
  *
  * TODO(paulberry):
  * - Add general.dart and html.dart for completeness.
  * - Use Graphviz's "record" feature to produce more compact output
  *   (http://www.graphviz.org/content/node-shapes#record)
  * - Produce a warning if a result descriptor is found which isn't the output
  *   of exactly one task.
  * - Convert this tool to use package_config to find the package map.
