Programming in Lua Notes
========================

Programming in Lua gives a solid base for any programmer who wants to use
Lua. It covers all aspects of Lua—from the basics to its API with C—explaining
how to make good use of its features and giving numerous code examples.
The book is targeted at people with some programming background, but it
does not assume any prior knowledge about Lua or other scripting languages.
