Description:
[Physics] General purpose Monte Carlo routines
This library contains three main routines. FOWL allows calculation of phase space distributions arising from particle interactions, generated in a Lorentz-invariant way. GENBOD is an N-body event generator, taking as input the center-of-mass energy, number and masses of outgoing particles. WICO traces a ray geometrically in a "Winston Cone" light concentrator. . Note that in order to compile and link programs against this library, you must also install the libphtools2-dev package.
