-SIMC has physics models for the following reactions.
-* Elastic and quasi-elastic scatering: H(e,e'p), A(e,e'p)
-* Exclusive pion production: H(e,e'pi+)n, A(e,e'pi+/-)
-(quasifree or coherent)
-* Kaon electroproduction: H(e,e'K+)Lambda,Sigma, A(e,e'K+/-),A(e,e'K-)
-* Semi-inclusive pion production: H(e,e'pi+/-)X, D(e,e'pi+/-)X
-* Semi-inclusive kaon production: H(e,e'K+/-)X, D(e,e'K+/-)X
-* Diffractive rho production: H(e,e'rho->pi+ pi-)p, D(e,e'rho->pi+
-pi-)

-## SIMC is NOT
-
-* Not a full detector response simulation a la GEANT/GEANT4
-* Does NOT simulate a large class of processes simultaneously to
-gerate backgrounds (like Pythia for example)
-* Not a generic event generator.  Processes are generated over a
-limited phase space matching the spectrometer acceptances
-* Not hard to modify
