 #   - castnow, https://github.com/xat/castnow
+#   - youtube-dl (https://youtube-dl.org/) or a drop-in replacement such as
+#     yt-dlp (https://github.com/yt-dlp/yt-dlp).
+#
+# Configuration:
+#   This script looks at the optional QUTE_CAST_YTDL_PROGRAM environment
+#   variable (if it exists) to decide which program to use for downloading
+#   videos. If specified, this should be youtube-dl or a drop-in replacement
+#   for it.
