{Package} [Glossary
Entry]
Packages are program units that allow the specification
of groups of logically related entities. Typically, a package contains
the declaration of a type (often a private type or private extension)
along with the declarations of primitive subprograms of the type, which
can be called from outside the package, while their inner workings remain
hidden from outside users.
