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 <discuss@en.tldp.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 (<ser@metalab.unc.edu>). Sections on DocBook were written by Jorge Godoy (<godoy@conectiva.com>). A great deal of thanks to both of them for their help.
