This book describes the code-generating software — The Integrated Chameleon Architecture — that assists in the task of translating between different representations of electronic data. This book discusses the various options for formulating solutions to the data translation problem and identifies those options that underlie the ICA architecture; walks step-by-step through a simple example in which translators are generated between L^ATEX and troff; presents detailed documentation of the ICA — with actual screens of the various states in the development of translators; and explains how to use the ICA to create SGML DTDs. Draws examples from the specifications used for building the translators for this book, itself — from a L^ATEX version of the manuscript to a (macro-based) troff version.
