;;; Commentary:
;;
-;; 'emms-stream-info' establishes a TCP connection with the server and
-;; sends an HTTP request string. The server (hopefully) responds with
-;; some header information describing the streaming audio channel,
-;; some audio data and then the name of the song being played (usually
-;; in that order).
-;;
-;; Some stations like WCPE [http://wcpe.org], while giving excellent
-;; broadcasts do not support title streaming over MP3 or Ogg. Using
-;; this software on such stations will only result in general station
-;; information and not the artist name or title of the track being
-;; played.
-
-;;; Functionality:
-;;
-;; Currently supports Icecast and Shoutcast servers with Ogg and MP3
-;; streams.
-
-;;; Use:
-;;
-;; Look at the documentation strings for the three interactive
-;; functions: 'emms-stream-info-get', 'emms-stream-info-message' and
-;; 'emms-stream-info-insert'.
-
-;;; Important Notes:
-;;
-;; 1) This software does not parse, cache or save audio data at
-;; all. This software downloads a limited amount of data from a
-;; given streaming audio channel per call. This software is
-;; optimized to download as little as possible from a given
-;; streaming audio channel and then to immediately disconnect.
-;;
-;; 2) This software disregards and then discards all audio data
-;; automatically after each call.
-;;
-;; 3) This software connects for a maximum of 10 seconds and then
-;; immediately disconnects. Usually the software will disconnect
-;; long before the 10 second limit is reached.
-;;
-;; 4) It is the responsibility of the user to read the Terms of
-;; Service of the streaming audio channel before running this
-;; software on that channel's service. Some streaming audio
-;; channels explicitly request 3rd party applications not to
-;; connect to their service. This is their prerogative. Respect it.

-;; A higher value for 'emms-stream-info-max' this gives us a
-;; correspondingly higher chance of grabbing the title information
-;; from a stream but incurs a price in the additional time it takes to
-;; download.
-;;
-;; This value is not relevant for Ogg streams since the title info in
-;; Ogg streams arrives almost immediately.
-;;
-;; Do not set under 30000 since the typical value of 'metaint' on most
-;; streaming audio servers is either 8192 or 24576
