+ (description "This library is a small interface to portable but
+nonstandard introspection of Common Lisp environments. It is intended to
+allow a bit more compile-time introspection of environments in Common Lisp.
+
+Quite a bit of information is available at the time a macro or compiler-macro
+runs; inlining info, type declarations, that sort of thing. This information
+is all standard - any Common Lisp program can @code{(declare (integer x))} and
+such.
+
+This info ought to be accessible through the standard @code{&environment}
+parameters, but it is not. Several implementations keep the information for
+their own purposes but do not make it available to user programs, because
+there is no standard mechanism to do so.
+
+This library uses implementation-specific hooks to make information available
+to users. This is currently supported on SBCL, CCL, and CMUCL. Other
+implementations have implementations of the functions that do as much as they
+can and/or provide reasonable defaults.")
