Tim Waugh : The Selfdocbook
"is a self-documenting introduction to DocBook DocBook book. It includes its own DocBook SGML source in the appendix, and so can be used to learn DocBook by example. ...if you see something that you want to know how to do, you can simply flip to Appendix A to find out how it is done."
Teledynamics : HTML2DB...the Holy Grail of DocBook Converters?
"Don't get too excited: Asking a robot to convert HTML to DocBook is like asking a machine to take a truckload of bricks and build you a house. Still, a robot can get you part of the way there; this package contains a shell script and a DSL file which take a first stab at converting well-formed HTML into quasi-DocBook-like markup. It's not the philosopher's stone, it can't possibly pass the NSGMLS test, but it might save you some work translating old HTML docs to DocBook."
