liblua5.1-0-dev 5.1.5-2 (i386 binary) in ubuntu quantal

 Lua is a powerful, light-weight programming language designed for extending
 applications. The language engine is accessible as a library, having a C
 API which allows the application to exchange data with Lua programs and also
 to extend Lua with C functions. Lua is also used as a general-purpose,
 stand-alone language through the simple command line interpreter provided.
 .
 This package contains developer resources for using the Lua library.
 Install it if you are developing programs which use the Lua C API, both
 in C or C++.
