description         Geant4 is a toolkit for the simulation of the passage of particles through matter.
long_description    Geant4 is 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. \
		    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.
