The hyperref package is used to handle cross-referencing commands in LaTeX to produce hypertext links in the document. The package provides backends for the \special set defined for HyperTeX DVI processors; for embedded pdfmark commands for processing by Acrobat Distiller ( dvips and Y&Y’s dvipsone); for Y&Y’s dviwindo; for PDF control within pdfTeX (pdftex) and dvipdfm ; for TeX4ht (tex4ht); and for VTeX’s pdf and HTML backends. The package is distributed with the backref and nameref packages, which make use of the facilities of hyperref.
