\\033[1mWhat's the point?\\033[0m
This script takes a single argument. Possible arguments are:
\\033[1;34m play, love, hate, next, stop, explain, playing, upcoming,
history, (next|prev|switch)station\\033[0m.
The behavior is mostly the same as running the respective action
inside pianobar, except you interact with notification bubbles.

THIS INTERACTION WILL ONLY WORK CORRECTLY IF YOU START PIANOBAR
THROUGH THE SCRIPT! SEE **USAGE** FOR INSTRUCTION.

This script is meant to be used as a hidden interface for
pianobar. It is invoked by keyboard shortcuts assigned by you, and
interacts with you through the use of pretty notification
bubbles. The point is that you are able to interact with pianobar
without having to focus the terminal you invoked it in. It also
shows album art, which pianobar can't do since it is terminal-
focused. If you prefer, you could also assign aliases instead of
keyboard shortcuts.

\\033[1;31mIMPORTANT:\\033[0;31m
This script depends on two commands: zenity and notify-send. As of
this writting libnotify-bin provides a buggy version of the
notify-send command in Ubuntu, so some options of the command don't
work. On Ubuntu, it is recommended that you install some patched[1]
version of the package that fixes the bug. Without this fix, you
might not get album art, and all your notification will have the
same duration of 10 seconds, which gets annoying fast. On other
systems, you'll get varying behavior. It is also recommended that
you create a file \".notify-osd\" in your \$HOME with the line
\"bubble-icon-size = 70px\". This will make the album art icons
bigger and more visible, but be aware that it will also affect
notifications from other software.\\033[0;30m

\\033[1mUSAGE:\\033[0m
Bind \"PATH/TO/control-pianobar.sh <argument>\" to a hotkey in your
distro's keyboard shortcut manager. Start pianobar with the command
\"PATH/TO/control-pianobar.sh p\" (or the appropriate hotkey.

\\033[1m Suggestions:\\033[0m

This script does take a second argument, but the user need not
worry about it. It's used by notify-pianobar.sh to make some
notifications behave right. If a second argument is provided, it
must be a positive integer. This number is the number of seconds the
script waits before running.

[1]From the date of this writting (2011) I am using a patched version
found in the ppa ppa:leolik/leolik. I take no responsibility
regarding the contents of this ppa, I'm simply stating it's the one
I used.
