build.xml

<!--
  This is a configuration file for use by Ant when building the
  Checker Framework.
  This top-level build file simply delegates to the subprojects.
  It assumes that the "checker" project is aware of all dependencies
  and that it is sufficient to run targets from there.

  Each subproject builds its own Javadoc including the documentation
  of all projects it in turn depends on. This would allow us to
  easily ship each subproject independently. Subprojects that
  already ship independently also build a Javadoc JAR file
  containing all its documentation.
