Dvips has support for producing hypertext PostScript documents. If you specify the `-z' option, the `html:' specials described below will be converted into `pdfmark' PostScript operators to specify links. Without `-z', `html:' specials are ignored.
The resulting PostScript can then be processed by a distiller program to make a PDF file. (It can still be handled by ordinary PostScript interpreters as well.) Various versions of both PC and Unix distillers are supported; Ghostscript includes limited distiller support (see section Ghostscript installation).
Macros you can use in your TeX document to insert the specials in the first place are available from `CTAN:/support/hypertex'. For CTAN info, see section `unixtex.ftp' in Kpathsea.
This hypertext support (and original form of the documentation) was written by Mark Doyle and Tanmoy Bhattacharya as the `dvihps' program. You can retrieve their software and additional documentation via the CTAN reference above. You may also be interested in the Java previewer IDVI, available at @url{http://www.win.tue.nl/~dickie/idvi}, and/or in @url{http://www.emrg.com/texpdf.html}, which describes the process of making PDF files from TeX files in more detail.
