JSON4Lua

JSON4Lua and JSONRPC4Lua implement JSON (JavaScript Object Notation)
encoding and decoding and a JSON-RPC-over-http client for Lua.
JSON is JavaScript Object Notation, a simple encoding of
Javascript-like objects that is ideal for lightweight transmission
of relatively weakly-typed data. A sub-package of JSON4Lua is
JSONRPC4Lua, which provides a simple JSON-RPC-over-http client and server
(in a CGILua environment) for Lua.
