      """Methods that simplify the setup of S3 generic functions and
      S3 methods. Major effort has been made in making definition of
      methods as simple as possible with a minimum of maintenance for
      package developers. For example, generic functions are created
      automatically, if missing, and naming conflict are automatically
      solved, if possible. The method setMethodS3() is a good start
      for those who in the future may want to migrate to S4. This is
      a cross-platform package implemented in pure R that generates
      standard S3 methods."""
