About
-----

This library entities define a *portable* operating-system interface for the
supported backend Prolog compilers. Some predicates may only be supported
by a subset of backend Prolog compilers on a subset of operating-systems.
They should be used with care and fully tested in your application domain
as some backend Prolog compilers have buggy and inconsistent interfaces,
specially across operating-systems.

The `os_types` category defines some useful operating-system types for
type-checking when using with the `type` library object.
