Detailed Description

This package provides various kinds of general basic utilities used in SSJ and also in the simulation laboratory at DIRO, Université de Montréal.

Much of this was originally implemented in the Modula-2 language before 1990 and has been translated in C and then in Java, with some adaptations along the road.
