Documentation is so very important when writing software. But some never learn: They write their documentation in Word! You can't make a worse choice. Luckily these documents are easily converted to the DocBook format. Infinite-loop made a java application called upCast to do the job. It converts Word documents to DocBook , by saving them to rtf first. Once you have a DocBook version of your documentation, you can start publishing it in whatever format you want using xslt stylesheets. A nifty little program, called DocMan, can process DocBook into html, xhtml, pdf, chm. In other words, you have one source of your documentation and different output formats.
