TODO

    * All exceptions thrown by mpfrcpp derive from a common base class
      that in turn derives from std::exception. That way all mpfrcpp
      exceptions can be caught with something less general than catching
      std::exception.

    * See the ``problems.txt''.

    * Should the default "abs" function use the input precision
      (as does operator-)?

    * List MPFR functions not wrapped in MPFRCPP for some reasons.

    * Add tests plotting graphics from function tables (via gnuplot).

    * Improve docummentation.

    * double-mpfr::Real operations (as optional feature).

I need volunteers' help:

    * Make GNU Coding Standards conforming package
      [http://www.gnu.org/prep/standards/].

    * Texinfo docummentation, man pages.

    * Test everything. Test on different compilers. Determine version
      requirements for popular programs.

    * More examples and tutorials (send me your questions and suggestions).

    * Efficient computations without constructing temporary objects. It should
      be implemented in elegant way, not like expression templates in GMP.
