In March 1996 I found an article in the German Unix magazine "iX" about Linuxdoc-SGML. It took two hours to download the Linuxdoc-SGML archive and to implement this format into UDO. Unfortunately I didn't own a Linux computer and so I wasn't able to test UDO's output.
Linuxdoc-SGML is a multiformat converter like UDO. With Linuxdoc-SGML you can convert SGML files into LaTeX, RTF, HTML, Texinfo and manpages. But it's not a lie if I say that UDO is more powerful than Linuxdoc-SGML 1.5.
