# xr – References to other LaTeX documents

The package provides a means of creating references to labels in another file (say, otherfile.tex) by reading that file’s auxiliary information from processing (otherfile.aux). This is achieved by the \externaldocument command, which also permits “relabelling” all of the external file with a prefix for all of its labels.

The package is part of the latex-tools bundle in the required distribution.
