+use copyparty as a file downloader by POSTing URLs as
+application/x-www-form-urlencoded (for example using the
+message/pager function on the website)
+
+example copyparty config to use this:
+  --urlform save,get -vsrv/wget:wget:rwmd,ed:c,e2ts:c,mtp=title=ebin,t300,ad,bin/mtag/wget.py
+
+explained:
+  for realpath srv/wget (served at /wget) with read-write-modify-delete for ed,
+  enable file analysis on upload (e2ts),
+  use mtp plugin "bin/mtag/wget.py" to provide metadata tag "title",
+  do this on all uploads with the file extension "bin",
+  t300 = 300 seconds timeout for each dwonload,
+  ad = parse file regardless if FFmpeg thinks it is audio or not
