+    (description "Lutok is a lightweight C++ API library for Lua.
+
+Lutok provides thin C++ wrappers around the Lua C API to ease the interaction
+between C++ and Lua.  These wrappers make intensive use of @acronym{RAII,
+Resource Acquisition is Initialization} to prevent resource leakage, expose
+C++-friendly data types, report errors by means of exceptions and ensure that
+the Lua stack is always left untouched in the face of errors.  The library
+also provides a small subset of miscellaneous utility functions built on top
+of the wrappers.
+
+Lutok focuses on providing a clean and safe C++ interface; the drawback is
+that it is not suitable for performance-critical environments.  In order to
+implement error-safe C++ wrappers on top of a Lua C binary library, Lutok adds
+several layers or abstraction and error checking that go against the original
+spirit of the Lua C API and thus degrade performance.")
