CUBPACK aims to offer a collection of re-usable code for automatic n-dimensional (n greater than or equal to 1) numerical integration of functions over a collection of regions, i.e., quadrature and cubature. The current version allows this region to consist of a union of n-simplices and n-parellellepids. The framework of CUBPACK is described as well as its user interface. The functionality of several well known routines is embedded. New features include integration algorithms using the epsilon-algorithm for extrapolation for regions other than triangles and the implementation of a new type of subdivision for 3-cubes.
