Geant4
======
A toolkit for the simulation of the passage of particles through matter. 
Its areas of application include high energy, nuclear and accelerator 
physics, as well as studies in medical and space science 
(http://www.geant4.org).

The two main reference papers for Geant4 are published in Nuclear 
Instruments and Methods in Physics Research A 506 (2003) 250-303, and IEEE 
Transactions on Nuclear Science 53 No. 1 (2006) 270-278.

This installer has been created using CPack (http://www.cmake.org).
