## Project history and usage

msgpack-tools is a small pair of Unix-style conversion utilities for MessagePack and JSON. The README lists `msgpack2json` for converting MessagePack to JSON and `json2msgpack` for the reverse direction, with options for lax JSON parsing, lossy conversions, pretty-printing, and base64 encoding. The AUTHORS file names Nicholas Fraser and Jerry Jacobs, and the changelog shows the project beginning as `msgpack2json` v0.1 before being renamed to msgpack-tools in v0.2.

### How it is used

The tool's role is practical glue around the MessagePack ecosystem. MessagePack itself is a compact binary serialization format supported across many languages; msgpack-tools lets developers inspect binary MessagePack payloads, convert hand-written JSON into MessagePack during builds, or test MessagePack-RPC services with shell pipelines and netcat. Its package-manager niche is intentionally small: a command-line bridge between human-editable JSON and binary MessagePack, overlapping with broader data remarshal tools but staying focused on two executables.
