Description:

Lutok provides thin C++ wrappers around the Lua C API to ease the
interaction between C++ and Lua. These wrappers make intensive use of
RAII 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.
