%description
Pythia can be used to generate high-energy-physics events, i.e. sets
of outgoing particles produced in the interactions between two
incoming particles.

%package -n %{soname}
Summary:        Shared library for Pythia - a simulation program for particle collisions
Group:          System/Libraries

%description -n %{soname}
Pythia can be used to generate high-energy-physics events, i.e. sets
of outgoing particles produced in the interactions between two
incoming particles. The objective is to provide as accurate as
possible a representation of event properties in a wide range of
reactions, within and beyond the Standard Model, with emphasis on
those where strong interactions play a role, directly or indirectly,
and therefore multihadronic final states are produced. The physics is
then not understood well enough to give an exact description; instead
the program has to be based on a combination of analytical results and
various QCD-based models. Extensive information is provided on all
program elements: subroutines and functions, switches and parameters,
and particle and process data. This should allow the user to tailor
the generation task to the topics of interest.

This package provides the shared libraries for %{name}.
