 LuaJIT is a Just-In-Time Compiler (JIT) for the Lua programming language.
 Lua is a powerful, dynamic and light-weight programming language. It may
 be embedded or used as a general-purpose, stand-alone language.
+
+LuaJIT 2.0 is compatible with Lua 5.1.

+This version of Lua isn't the most recent version but it's still widely
+used, due to popularity of LuaJIT 2.0 which is compatible with Lua 5.1.
