Currently, the files for Fritiof are:

fritiof_7.02 
aiadne_402r.f
jetset_73B.f
pythia_55.f

Version info. was dropped from the  original file name.


Zlujets.h must present in Particle/Event/Interface, too.
The same common as /arjetx/ given in Zarjetx.h must be
given in fritiof.f;  the igredient names must be different
so that it can interface /lujets/.
function rlu in jetset has been replaced by rndc so that
the random number generation be  controled by Cosmos.

When using 'new1/2', one must be careful that if the
energy and 'fixt' or 'cms' specifications are the same
as the previous call, Fritiof judges that the input
parameters are the same as the previous call even if
the contents of 'new1/2' is changed.
