description         OpenCL Fortran 90 interface
long_description    \
   FortranCL is an OpenCL interface for Fortran 90. \
   It allows programmers to call the OpenCL parallel programming framework \
   directly from Fortran, so developers can accelerate their Fortran code \
   using graphical processing units (GPU) and other accelerators.
