The first version of the package (as well as the subsequent version 2.1) was released in 2006, when the first author was a postdoctoral research collaborator at the Vrije Universiteit Brussels, Belgium. It is a pleasure of the first author to express his gratitude to Prof. Dr. Eric Jespers for his warm hospitality and to acknowledge the support provided by the Francqui Stichting grant ADSI107.

Both authors are very grateful to the members of the &GAP; team: Thomas Breuer, Stefan Kohl and Frank Lübeck for helpful suggestions. We would like to acknowledge Bettina Eick for communicating the package, and the referee for testing &UnitLib; and useful commnets. Finally, we wish to thank the Centre for Interdisciplinary Research in Computational Algebra of the University of St Andrews and the Computational Cluster of the Kiev National Taras Shevchenko University for offering their computer facilities for computations.
