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 <[email protected]> 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 protected]>). Sections on DocBook were written by Jorge Godoy (<[email protected]>). A great deal of thanks to both of them for their help.
