MOP-features
This package provides a way to check what features a Common Lisp implementation supports. The simplest way to use it is to load it with asdf, use the :mop-feature-tests package and execute the functions run-feature-tests and describe-mop-features without parameters.

MOP Features is written and maintained by Pascal Costanza. See Common-Lisp.net for more information.
