The refstyle provides a consistent way of producing references throughout a project. Enough flexibility is provided to make local changes to a single reference. The user can configure their own setup. refstyle has a direct interface to varioref, and namedref's from the namedref package can easily be incorporated (if needed). For large projects such as a series of books or a multi volume thesis, written as freestanding documents, a facility is provided to interface to the xr package for external document references.
