This book was produced by Cogent Real-Time Systems, Inc. from a single-source group of SGML files. Gnu Emacs was used to edit the SGML files. The DocBook DTD and related DSSSL stylesheets were used to transform the SGML source into HTML, PDF, and QNX Helpviewer output formats. This processing was accomplished with the help of OpenJade, JadeTeX, Tex, and various scripts and makefiles. Details of the process are described in our book: Preparing Cogent Documentation, which is published on-line at
