Packages
A package is a set of routines and data types that forms a part of the Toolbox or
Operating System and is stored as a resource. On the original Macintosh
computer, all packages were disk-based and brought into memory only when
needed; some packages are now in ROM.
The System file contains the standard Macintosh packages and the resources
they use or own.
