 The *purpose of a package* is to be a simple, and easy to access, code sharing medium, which will allow: on the one hand, to separate the code complex dependencies created by the developer from the user experience with the final product and, on the other hand, reduce developer's and user's unnecessary frustration related to a remote deployment process.
