If you have a document built under SGML-based DocBook, follow these steps to convert it to XML.
Replace the <!DOCTYPE...>
declaration at the top of your document with the one
from the first two lines of the model file
in your working directory (assuming you followed the
directory setup
procedure above), or use /u/www/docs/tcc/help/pubs/docbook43/user-kit/model.
If you use pictures and other graphics, refer to the section above on including graphics. At this writing, only JPG and GIF formats are supported.
