Handling the rsync SGML documentation
rsync documentation is now primarily in Docbook format. Docbook is an SGML/XML documentation format that is becoming standard on free operating systems. It's also used for Samba documentation.
The SGML files are source code that can be translated into various useful output formats, primarily PDF, HTML, Postscript and plain text.
To do this transformation on Debian, you should install the docbook-utils package. Having done that, you can say
docbook2pdf rsync.sgml
and so on.
On other systems you probably need James Clark's "sp" and "JadeTeX" packages. Work it out for yourself and send a note to the mailing list.
