"""Standalone Lauther plugin for Apprise — no upstream install needed.

Use this TODAY with any Apprise >= 1.0 via a custom plugin directory:

    apprise --plugin-path /path/to/this/folder \
        -t "Title" -b "Body" lauther://lpt_YOURTOKEN

or drop it into ~/.apprise/plugins/ (Linux/macOS) /
%APPDATA%/Apprise/plugins (Windows), where Apprise auto-loads it.

Tools that embed Apprise with custom-plugin support pick it up the same way.
Syntax:  lauther://lpt_TOKEN  (optional: ?priority=-2..2)
