33// Description:
34// Class to generate inclusive non-resonant B -> Xs l+ l- decays.
35// Description: Routine to generate non-resonant B -> Xs l+ l- decays.
36// It generates a dilepton mass spectrum according to Kruger and Sehgal
37// and then generates the two lepton momenta accoring to Ali et al.
38// The resultant X_s particles may be decayed by JETSET.
