-For SGML output (not actively maintained any more):
-
-The DocBook SGML DTD.
-    http://www.oasis-open.org/docbook/

-Jade v1.1 or OpenJade 1.3.1.
-    http://www.jclark.com/jade
-    http://sourceforge.net/projects/openjade
-
-The DocBook DSSSL Stylesheets (I've got 1.40, but v1.19+ may be OK).
-    I've customized the DSSSL code slightly, in gtk-doc.dsl, to colour
-    the program code listings/declarations, and to support global
-    cross-reference indices in the generated HTML.

 Most distributions now have packages for all of these, so I would strongly
 advise that you grab those.
