+;;; test-music-config--m3u-entries.el --- Tests for #EXTINF/UUID/favicon parse -*- coding: utf-8; lexical-binding: t; -*-
+;;
+;; Author: Craig Jennings <c@cjennings.net>
+;;
+;;; Commentary:
+;; Unit tests for `cj/music--m3u-entries': parse .m3u text into an alist of
+;; (stream-url . plist), each plist carrying :name (the #EXTINF label), :uuid
+;; (#RADIOBROWSERUUID), and :favicon (#RADIOBROWSERFAVICON).  This is the one
+;; pure parser both the name resolution (Phase 1) and the cover-art layer read.
