+  The HepMC package is an object oriented event record written in C++
+  for High Energy Physics Monte Carlo Generators. Many extensions from
+  HEPEVT, the Fortran HEP standard, are supported: the number of entries
+  is unlimited, spin density matrices can be stored with each vertex,
+  flow patterns (such as color) can be stored and traced, integers
+  representing random number generator states can be stored, and an
+  arbitrary number of event weights can be included. Particles and
+  vertices are kept separate in a graph structure, physically similar to
+  a physics event. The added information supports the modularisation of
+  event generators. The package has been kept as simple as possible with
+  minimal internal/external dependencies. Event information is accessed
+  by means of iterators supplied with the package.
