%global _description %{expand:
MEPACK is a software library focused on solving dense Sylvester-like
matrix equations. The library is written in Fortran and provides
interfaces for C, MATLAB and GNU Octave. The development places great
emphasis on the fact that the algorithms can be adapted very well to
modern CPU architectures by current Fortran compilers. In addition, the
algorithms are accelerated through the use of directed acyclic graphs
using OpenMP to increase the utility of multicore architectures.
