MqttExplorer is a native MUI (Magic User Interface) application for
classic AmigaOS. It connects to an MQTT broker, shows every topic it
publishes as a live-updating tree, lets you inspect any message, and
publish your own - a small, on-target equivalent of the desktop MQTT
Explorer tool.

Status: work in progress (v0.1). Connecting, subscribing, publishing and
the live topic tree have been verified on real hardware/WinUAE, but this
is still under active development, not a finished/polished release.

Requirements
------------
  - AmigaOS 3.1+, 68020 or better.
  - MUI 3.8+/4.x (with Listtree.mcc - ships with any standard install).
  - A TCP/IP stack providing bsdsocket.library.
  - midge's mqtt.library, copied to LIBS: - MqttExplorer is built on top
    of it and will not run without it.
    https://github.com/sidick/midge / https://sidick.github.io/midge/
  - Optional, for TLS brokers: AmiSSL 5.x, installed separately.

Quick start
-----------
  Copy midge's mqtt.library to LIBS:
  Run MqttExplorer, fill in your broker's Host/Port, press Connect.

See MqttExplorer.guide for the full user manual (AmigaGuide format).
