** USAGE
 Make sure you have your media keys (or whatever) mapped to the appropriate
 keysyms (using =xmodmap=), then put:
#+BEGIN_SRC lisp
            (load "/path/to/amixer.lisp")
#+END_SRC
 ...in your =~/.stumpwmrc=, followed by some keybindings (according
 to your preference)

Example keybindings:
#+BEGIN_SRC lisp
            (define-key *top-map* (kbd "XF86AudioLowerVolume") "amixer-Front-1-")
            (define-key *top-map* (kbd "XF86AudioRaiseVolume") "amixer-Front-1+")
            (define-key *top-map* (kbd "XF86AudioMute") "amixer-Master-toggle pulse")
#+END_SRC
 =amixer= commands take an optional parameter, the device parameter
 as passed to the =-D=. This can be useful if you are running pulseaudio.

** Tasks

*** TODO Make the `defvolcontrol' macro create all the necessary commands at once.
 - Should it just create, say, amixer-pcm, which would be passed an
   argument? i.e., (define-key *this-map* (kbd "e") "amixer-pcm 1-")
 - Else, figure out how to make the macro not error when converting a
   string to a symbol for the name of the command
