The hyperTeX project

The hyperTeX project extended the functionality of all the LaTeX cross-referencing commands (including the table of contents) to produce \special commands which are parsed by DVI processors conforming to the HyperTeX guidelines; it provides general hypertext links, including those to external documents.

The HyperTeX specification says that conformant viewers/translators must recognize the following set of \special commands:

href:

|html:|

name:

|html:|

end:

html:

image:

|html:|

base_name:

|html:|

The href, name and end commands are used to do the basic hypertext operations of establishing links between sections of documents.

Further details are available on http://arXiv.org/hypertex/; there are two commonly-used implementations of the specification, a modified xdvi and (recent releases of) dvips. Output from the latter may be used in recent releases of ghostscript or Acrobat Distiller.
