0. Preface
This volume will show several ways for speeding up Ruby code, by
replacing a small amount of time-critical Ruby lines by short C functions.
We have started writing some text here, but the bulk of the text will
appear later, by late 2004 or early 2005.
0.1. Acknowledgments
We thank xxx, xxx, and xxx for their comments on the
