  APACIC++ is a Monte-Carlo event-generator dedicated for the simulation of
electron-positron annihilations into jets. Within the framework of APACIC++,
the emergence of jets is identified with the perturbative production of partons
as governed by corresponding matrix elements. In addition to the build-in
matrix elements describing the production of two and three jets, further
programs can be linked allowing for the simultaneous treatment of higher
numbers of jets. APACIC++ hosts a new approach for the combination of arbitrary
matrix elements for the production of jets with the parton shower, which in
turn models the evolution of these jets. For the evolution, different ordering
schemes are available, namely ordering by virtualities or by angles. At the
present state, the subsequent hadronization of the partons is accomplished by
means of the Lund-string model as provided within Pythia. An appropriate
interface is provieded.
  The program takes full advantage of the object-oriented features provided by
C++ allowing for an equally abstract and transparent programming style.
