A lot of features have been covered in this chapter, but only a small handful are needed for the
MovieMan module we're about to implement. We'll put more of them to use as we add to the project in later chapters. Throughout the book, the full path of any example source module is referred to as
$LEARNINGD/ChapterNum/filename.d. This is impractical for the
MovieMan code listings, as the project will be implemented across multiple chapters. When referring to
MovieMan source modules, the form
$MOVIEMAN/filepath/filename.d will be used, where
$MOVIEMAN is the root directory of either the DUB project we created in the first chapter or of any other location you choose to initialize the
MovieMan project with DUB.
