11. A computer-readable storage medium comprising instructions for performing a method for identifying an external program code dependency, the method comprising: executing compiler functionality upon a code base to generate compilation parameters indicative of external programming code dependencies between one or more entities within the code base and one or more external program code modules, the compilation parameters not predefined before execution of the compiler functionality; determining an external program code dependency indicative of a dependency between an entity within the code base and an external program code module based upon the compilation parameters, the external program code dependency comprising an indication of a source associated with the external program code module; and utilizing the external program code dependency to automatically port a computer application associated with the code base from a first computing system to a second computing system, at least one of the execution of the compiler functionality and the determination of the external program code dependency being automated.
12. The computer-readable storage medium of claim 11 , comprising: mapping the external program code dependency to a second external program code module associated with the second computing system.
