...JAGAL builds upon the Java library TOVAL (located at http://sourceforge.net/p/toval). To use JAGAL, make sure the TOVAL library is on the build path.
This library uses and encloses jGraphX (https://github.com/jgraph/jgraphx).
A documentation for JAGAL can be found under http://doku.telematik.uni-freiburg.de/jagal.
