In the recent years there has been an enormous development in the evaluation
of higher order quantum corrections.
An essential ingredient in the practical calculations is provided by vacuum
diagrams, i.e. integrals without external momenta.
In this paper a program package is described which can deal with one-, two-
and three-loop vacuum integrals with one non-zero mass parameter.
The principle structure is introduced and the main parts of the package are
described in detail. Explicit examples demonstrate the fields of application.
