Style #20

Constraints:

The problem is decomposed using some form of abstraction (procedures, functions, objects, etc.)
All or some of those abstractions are physically encapsulated into their own, usually pre-compiled, packages. Main program and each of the packages are compiled independently. These packages are loaded dynamically by the main program, usually in the beginning (but not necessarily).
Main program uses functions/objects from the dynamically-loaded packages, without knowing which exact implementations will be used. New implementations can be used without having to adapt or recompile the main program.
External specification of which packages to load. This can be done by a configuration file, path conventions, user input or other mechanisms for external specification of code to be linked at run time.
