Lua is a simple, expressive, extension programming language that is easily
embeddable. Lua::API provides Perl bindings to Lua's C-based embedding
API. It allows Perl routines to be called from Lua as if they were written
in C, and allows Perl routines to directly manipulate the Lua interpreter
and its environment. It presents a very low-level interface (essentially
equivalent to the C interface), so is aimed at developers who need that
sort of access.
