This is COMPASS event generator for double pomeron exchange processes in PP collisions modified for ALICE experiment.
C++ interface provides acces beetween fortran routines and AliRoot framework. 

Currently generates pp->pXp reaction where X decays into pi+pi- pair.
Process numbers:
1 -- generates continuum mass spectrum
2 -- generates f0(500)
3 -- generates rho0(770) (which is not expected in Pomeron-Pomeron fusion)
4 -- generates f0(980)
5 -- generates f2(1270) (isotropic decay = S-wave)
6 -- generates f2(1270) D0 wave in Gottfried-Jackson frame (Pomeron along z-axis)
7 -- generates f2(1270) 50%D+ 50%D- waves in Gottfried-Jackson frame (Pomeron along z-axis)
8 -- generates f2(1270) D0 wave in GJ' frame (proton along z-axis)
9 -- generates f2(1270) 50%D+ 50%D- waves in GJ' frame (proton along z-axis)
10-- generates f2(1270) user-setted polarization in Gottfried-Jackson frame (Pomeron along z-axis)
11-- generates f2(1270) user-setted polarization in GJ' frame (proton along z-axis)
