libgrengine-java - 3.1.0+dfsg-1 main

Grengine allows one to run Groovy code in a Java VM, in a way that is quick,
highly configurable and thread-safe. When the default behavior does not suit
the users' needs, classes can be overridden to change the way the framework
behaves. Even without writing new classes, there are ways to configure the
engine quite a lot.
