Lua Cjson Library

Lua CJSON is a Lua C module that provides fast JSON parsing and encoding support for Lua.

Project homepage: http://www.kyne.com.au/~mark/software/lua-cjson.php

OpenResty includes its own fork of this library, however. The repository of OpenResty's fork is on GitHub:

https://github.com/openresty/lua-cjson/

This library is enabled by default. You can specify the --without-lua_cjson option to OpenResty's ./configure script to explicitly disable it.
