To move from one language to another (Pacal -> C for instance) isn't
necessarily a rewrite as you are simply duplicating the functionality
as opposed to making new. This is known as porting to another
language.

You also can port from one compiler to another or one toolkit to
another. As you get more advanced, such as the toolkit level, you
start getting into rewriting since the API's become wildly different.
