Given a functioning SGML environment, all of the necessary files are shown in full in this appendix. All you have to do in order to build the Selfdocbook is:
Make sure you that have installed the necessary SGML tools.
In addition to those tools you will need:
fig2dev for converting image formats
fold and sed for manipulating SGML files so that they can be included verbatim in a DocBook document.
Put all the files in the same directory and type make. The default target builds PostScript, PDF and HTML output.
