+;;; Commentary:
+
+;; This file defines a few simple functions to raise or lower the volume
+;; using amixer. It can be used stand-alone, though it's meant for usage
+;; with EMMS, particularly with emms-volume.el
+
+;;; History:
+
+;; May 30 2006: First cleanup and collation of amixer functions into a
+;;              separate file for releasability.
+
+;;; Todo:
+
+;; There probably needs to be more configurability, which may in turn
+;; mean adding some more functions.
+;; Some of this could benefit from adding customize interfaces.
+
+;;; Code:
+
+(defun emms-volume-amixer-sset-master (var)
+  "Change amixer master volume by VAR."
+  (start-process "mixer" nil "amixer" "sset" "Master" var))

+;;; Commentary:
+;; 
+;; This file provides generally two things:
+;; Generic volume setting functions and some appropriate bindings for EMMS
+;; playlist buffers. These can also be bound to global keys,however, the
+;; second part may be more useful for this. This part provides functions
+;; meant to be bound to a global key (the author uses C-c e + and C-c e -),
+;; which then temporarily activates a minor mode allowing you to change the
+;; volume with just + and -. This mode deactivates a short (configurable)
+;; amount of time after the last volume change. This allows for easier volume
+;; adjustment without getting in the way.

+
+;; May 2006: First stab at writing the minor mode.

[emms-streams: When the user wants emms-streams to play the selected stream 
instead of add it, create our own playlist buffer.  When quitting, if we own 
the current playlist buffer, kill it.

[emms-streams: Re-implement yank and kill so that they do the right thing with 
emms-stream-list.

[allow nonzero ogginfo exit plus some reindenting
Martin Schoenmakers <address@hidden>**20060530130411
 
 When ogginfo gave a nonzero value on exit, any valid data would get tossed
 if there was any. This prevented emms from showing info for files that are
 tagged but a bit odd.
 
 Also reindented emms-info-ogginfo accordingly, which incidentally removed
 some tabs in favour of spaces.

[emms-streams: Implement kill and yank.
