Many years ago I worked at a DEC-shop. We used a tool called Document (as far as I remember) to create documentation. It was provided by DEC and created the same layout as the original DEC documentation. Which is as far as I'm concerned a milestone in layout and typesetting.
Researching the web I found a more or less obscure company which sells this tool for Open VMS. But I would prefer an open source replacement.
Any help ?

Touch Technology was, and perhaps still is, an interesting company with interesting folks like 'Mr Dan'. They picked up a good bit of Digital software in a fire-sale and had some good stuff such themselves such as performance tuning tools and a 4GL (Intouch... available on OpenVMS Freeware). The company appears to have moved one, judging by their current website front door which does not dwell on the old stuff , but you could do worse than try contact them. The back door still list DECdocument: http://www.ttinet.com/documentation.html
Good luck! Hein
