Docbook: tool I used for most documentation
Docbook is an XML documentation standard I used a lot in "eConstruct":.. and in my masters thesis.
Docbook is an XML standard for typing in books, articles, program documentation, etcetera. For those who know latex, it follows basically the same principles. It's rapidly becoming the standard for documentation of OpenSource software, though it didn't start out in that field. I used it to make my MastersThesis and I've never regretted it.
