Provides support for accessing local installation information.

Package Specification

This package contains interfaces for accessing and manipulating the local system installation and configuration information. In general, users extending the update support  by writing additional feature and site implementation do not need to make use of interfaces defined in this package.

Note: This package is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
