# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

$PRGNAM: $PRGNAM (computer-science text)
$PRGNAM:
$PRGNAM: Wizard Book n. Hal Abelson's, Jerry Sussman's and Julie Sussman's
$PRGNAM: Structure and Interpretation of Computer Programs (MIT Press, 1984;
$PRGNAM: ISBN 0-262-01077-1), an excellent computer science text used in
$PRGNAM: introductory courses at MIT. So called because of the wizard on the
$PRGNAM: jacket. One of the bibles of the LISP/Scheme world. Also,
$PRGNAM: less commonly, known as the Purple Book.
