While studying the representations of quivers from the point of view of Invariant Theory, that is, orbits, orbit closures, locally closed orbits, and semi-invariants, I realized that many natural questions such that generic decompositions, perpendicular categories etc. may be calculated systematically, by means of the corresponding algorithms. It was then natural to implement the algorithms and provide a user with a convenient graphic interface. Currently this is done under Windows and you may download the program and the corresponding help file, where you will find more details:
