This book accumulates the information that I have written about TOM in the past four years. That's exactly four years, as I happen to be writing this preface on 16 November 1999, TOM's fourth birthday.

The TOM Tome is written in DocBook. When it is finished, I expect to know a lot about DocBook. At the moment, all I know is that it appears to be a good decision.

In its current form, this book needs an editor's hand. However, my priority is to get all the information in, instead of presenting it in a pleasant way. Having all the information in one place already offers much progress over the previous situation where information was dispersed in many locations.
