What's the story behind the camel?
An old joke on commitees stated, "A camel is a horse designed by a committee"; similar to saying a jack of all trades is master of none.
Since Larry Wall first came up with Perl as amalgam of several different languages (Bourne shell, awk, sed, even BASIC-PLUS) it was a sort of "design by commitee": a camel of programming languages.
My memory's a little foggy, but IIRC the association was there even before the Camel book was published, so the cover choice was a natural one. Maybe TimToady or merlyn will remember more clearly which came first.
