  5. * LibTomMath is a library that provides multiple-precision
  6. * integer arithmetic as well as number theoretic functionality.

  8. * The library was designed directly after the MPI library by
  9. * Michael Fromberger but has been written from scratch with
  10. * additional optimizations in place.
  11. *
  12. * The library is free for all purposes without any express
  13. * guarantee it works.
