The package 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. The package offers a direct interface to
varioref (for use, for example, in large projects such as a
series of books, or a multivolume thesis written as a series of
documents), and name references from the nameref package may be
incorporated with ease. 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.
