Macros and functions for signalling and handling errors and other
unexpected situations.  It's patterned after the Symbolics condition
handling system, but the names and syntax of many operators and conditions
have been changed.

It's mostly the same.  A few features have been added (such as the OF-TYPE
preposition for declaring types using Common Lisp type specificiers), some
descriptions have been clarified, and a few obscure features have not been
included.  We also didn't include the facilities for writing user-defined
LOOP paths (DEFLOOP and DEFINE-LOOP-PATH).  Most of the features that were
removed or clarified already differed between various LOOP implementations;
most portable uses of LOOP should port to the ANSI version.
