Description

Implementation of the command frontend.

Within this file, the implementation level of the command frontend is linked to the implementation of the command registry. Client code is shielded from those implementation classes and need only include command.hpp

More specifically, the actual number and type of arguments and the concrete functions implementing the command operation are known only at the time of the command definition; this detailed type information is erased afterwards, allowing client code to use a simple frontend.
