Most of the tar and zip code was nicely split out into two abstracted files which knew only about their specific formats. The entry point to this code was a single "write archive" function. However, as these basic formats grow more complex (e.g., by handling multiple file extensions and format names), a static list of the entry point functions won't be enough. Instead, let's provide a way for the tar and zip code to tell the main archive code what they support by registering archiver names and functions.
