%description
EvtGen is a Monte Carlo event generator that simulates the decays of 
heavy flavour particles, primarily B and D mesons. It contains a range
of decay models for intermediate and final states containing scalar, 
vector and tensor mesons or resonances, as well as leptons, photons 
and baryons. Decay amplitudes are used to generate each branch of a 
given full decay tree, taking into account angular and time-dependent 
correlations which allows for the simulation of CP-violating
processes. Originally written by Anders Ryd and David Lange, this 
package is used by many particle physics experiments worldwide,
including BaBar, Belle(-II), CLEO(-c), CDF, D0, LHCb, ATLAS and CMS.
The maintenance and development of the package is now performed by 
the particle physics group at the University of Warwick (in 
particular by John Back, Thomas Latham and Michal Kreps).
