geant321-doc package - README.Debian
--------------------
The documentation available here is as follows. In parentheses ( ) are the
names that these files originally had in the Cernlib source tree. The section
of the GEANT3 code described by each document is given in square brackets [ ].
In addition to this documentation, you should look at the README.Debian
for the geant321 or libgeant1-dev package - it describes some functions and
subroutines that had to be removed in order for GEANT to be DFSG-free.
