Thanks to everyone that gave comments as I was writing this. This includes David Lawyer, Deb Richardson, Daniel Barlow, Greg Ferguson, Mark Craig and other members of the <firstname.lastname@example.org> list. Some sections I got from the HOWTO Index and the sgmltools documentation. The sections on network access to CVS was partially written by Sergiusz Pawlowicz (<email@example.com>). Sections on DocBook were written by Jorge Godoy (<firstname.lastname@example.org>). A great deal of thanks to both of them for their help.
Thanks to Tabatha Marshall and Machtelt Garrels (Tille) for making sure I actually finished the document. Thanks to my reviewers: Charles Curley, Martin Brown and Tille; and to Saqib Ali for his on-line transformation and validation tools. I have also incorporated a number of useful emails from the LDP mailing lists. The original authors are credited within the document. Special personal thank yous are extended to Steve Champeon for getting me interested in markup languages and for being a wonderful mentor; and to my partner, Graig Kent, for being outrageously supportive.
