+This distribution implements event-level parallelism for
+ <a href="http://cern.ch/geant4">Geant4</a>
+  using the free TOP-C distribution.
+  (<a href="http://www.ccs.neu.edu/home/gene/topc.html">TOP-C
+      = Task Oriented Parallel C/C++</a>)
+
+<P>
+These are example parallelizations that parallelize examples/novice/N02
+and examples/novice/N04 of the Geant4 distribution.
+The files also contain information on how to write new parallel
+Geant4 applications or parallelize existing sequential Geant4
+applications.
+
+<P>
+<PRE>
+The design goals are:
+1.  No modification of the Geant4 kernel libraries.
+2.  Application sessions should be efficient and reproducible
+     (independently of the number of slave processes and the
+      order in which they are called by TOP-C)
+3.  Setting deterministic random seeds on each slave
+    [ This code assumes that each slave will initialize its random state
+      based on either the event number or a random seed selected
+      on the master.]
+
+This assumes that you have already installed CLHEP, Geant4, and TOP-C
+  TOP-C can be downloaded via its home page:
+                          http://www.ccs.neu.edu/home/gene/topc.html
+
+Other qualifications are:
+1.  `topc-config' is already in your path.
+2.  It has only been tested under Linux, although it should be
+       portable to any other UNIX supported by Geant4.
+3.  Currently, this distribution does not support:
+      histograms, trajectory stores, n-tuples, track parallelism,
+      interactive input commands (no macrofile)
+    I plan to add those features according to demand.
+       Probably:  a. histograms (I believe histograms work now, but I don't
+                        have a ready test application.  If someone does, could
+                        you either check yourself if the parallelization works
+                        for histograms, or tell me, and I'll parallelize it.)
+                  b. track-level parallelism
+                  c. allowing interactive input
+                  d. other

+Some design assumptions of Geant4 used here:
+1.  A collectionName for a G4HitsCollection uniquely identifies the
+      G4HitsCollection within a G4HCofThisEvent.
