XLUnit provides a unit testing package for Common Lisp.  It it based
on the XPTest package by OnShore development, but is rewritten to be
closer in usage to the JUnit package.

XLUnit it is designed to be used with significantly less overhead on
the part of the test author compared to XPTest. Most powerfully,
XLUnit can create dynamic test suites based on defined methods.

XLUnit comes with its own test suite (tests.lisp) along with an
example file (example.lisp).
