 This class describes a PROOF slave server.                           
 It contains information like the slaves host name, ordinal number,   
 performance index, socket, etc. Objects of this class can only be    
 created via TProof member functions.                                 
                                                                      


TSlave(const char *host, Int_t port, Int_t ord, Int_t perf, const char *image, Int_t security, TProof *proof)
 Create a PROOF slave object. Called via the TProof ctor.

~TSlave()
 Destroy slave.

void Close(Option_t *)
 Close slave socket.

Int_t Compare(const TObject *obj) const
 Used to sort slaves by performance index.

void Print(Option_t *) const
 Printf info about slave.

void SetInputHandler(TFileHandler *ih)
 Adopt and register input handler for this slave. Handler will be deleted
 by the slave.
