Thanks to all the friends who helped (or tried to) and to my husband; your encouraging words made this work possible. Thanks to all the people who submitted bug reports, examples and remarks - among many, many others:
Hans Bol, one of the groupies
Mike Sim, remarks on style
Dan Richter, for array examples
Gerg Ferguson, for ideas on the title
Mendel Leo Cooper, for making room
#linux.be, for keeping my feet on the ground
Frank Wang, for his detailed remarks on all the things I did wrong ;-)
Special thanks to Tabatha Marshall, who volunteered to do a complete review and spell and grammar check. We make a great team: she works when I sleep. And vice versa ;-)
