[Gate-users] precise multileaf collimator(MLC )simulation on GATE

[????]

hi  gate users:
    I do simulation of multileaf collimator (MLC)on GATE , there is some unexplained  abbreviation such as  KILL PLANE ,TRPD SUP TRPD INF  in macro sentence,any one can help me?  Who has done the simulation of MLC ,Can you give a guide ? The following is:

## KILL PLANE
