cl-utilities - 1.2.4-3.2 main

On Cliki.net , there
is a collection of Common Lisp Utilities, things that everybody writes
since they're not part of the official standard. There are some very
useful things there; the only problems are that they aren't
implemented as well as you'd like (some aren't implemented at all) and
they aren't conveniently packaged and maintained. It takes quite a bit
of work to carefully implement utilities for common use, commented
and documented, with error checking placed everywhere some dumb user
might make a mistake.
