### Making hypertext documents from TeX

If you want on-line hypertext with a (La)TeX source, probably on the World Wide Web, there are four technologies to consider:

- Direct (La)TeX conversion to HTML;
- Use Texinfo, and use the info viewer, or convert the texinfo to HTML;
- Use Adobe Acrobat, which will preserve your typesetting perfectly (see Making Acrobat documents from LaTeX);
- The hyperTeX conventions (standardised `\``special` commands); there are supporting macro packages for Plain TeX and LaTeX).

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:<a href = "href_string">`
name:
  `html:<a name = "name_string">`
end:
  `html:</a>`
image:
  `html:<img src = "href_string">`
base_name:
  `html:<base href = "href_string">`

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.
