Special instruction for upgrading to SuSpect2.31 codes already interfaced 
previously with suspect2.3:

NB: though we have made our best to minimize the amount of necessary
upgrade to do in an already existing interface, 
a few changes are however unavoidable. They are all summarized below.
Normally you only need to replace the suspect2.f, suspect2_call.f 
files with their new version; and to add the SLHA format input file: 
suspect2_lha.f.
However, it may be helpful to know that in the suspect2.f main file 
have been added two new subroutines: 
1) to read input file in the SLHA format:
        subroutine SU_read_leshouches(ninlha,ichoice,imod)

2) to write output file in the SLHA format:
     subroutine su_lhaout(nout,ichoice,errmess,imod)
(see eventually details in these subroutines)
-the parameters nl, nq (nb of lepton/ quark messengers in GMSB models)
HAVE BEEN CHANGED from "integer" to (double precision) real
(for compatibility with SLHA formats):
       double precision nl,nq
thus integer declaration to real declaration was changed in
-main routine
-subroutine  SU_GMSBSUB
-subroutine SU_read_leshouches
-subroutine su_lhaout
- additional calculation lines related to b->s gamma, g_mu -2, etc
added in main subroutine, and corresponding additional material
in writing output sections;
-NO other modifications (in particular no bugs found or corrected
since previous (June 16, 2004) version).
