The ant tasks for Cobertura and assorted helper classes.

The license for the ant tasks is different than the license for the rest of Cobertura (Apache Software License version 1.1 v. GPL version 2). The GPL prohibits linking GPL-licensed code with code licensed under a GPL-incompatible license such as the Apache Software License version 1.1. For this reason, the Cobertura ant tasks do not directly invoke the Cobertura classes. Rather, they invoke a JVM which runs the Cobertura classes.
