 Hi Jacek,

 TGeant4, TGeant3 classes were implemented
 to be independent on the rest of the AliRoot:
 you will need to take TGeant4 directory
 and AliGeant3/T* classes. 

 However as we keep the interfaces in the same 
 package (and library) as the other core
 classes for AliRoot - STEER - you will need
 also these few Ali* classes:
   AliMC      - interface for Monte Carlo
   AliDecayer - interface for external decayer
   AliMCProcess - enumeration
  ---
   AliPDG      - for TGeant3
   AliCallf77
 I hope that is all - but I didn't try myself.

 In AliRoot, we provide GEANT321 and MINICERN
 packages with G3 + cernlib stuff; Geant4 is used as
 external package.

 We have not "novice" examples,
 besides AliRoot itself the AliRoot framework
 was adopted by OPERA collaboration at
 Institut de Physique Nucleaire de Lyon
 - but they took the whole framework
 not only extracted MC interface related
 part.

 Best regards,

 Ivana
