+# INFO
+###
+#
+#  Type this to add the item:
+#
+#    /statusbar window add df
+#
+#  See
+#  
+#    /help statusbar
+#
+#  for more help on how to custimize your statusbar.
+#
+#  If you want to change the way the item looks, browse down to where it reads
+#
+#  $output .= ' [' . $device . ': A: ' . $avail{$device} . ' U%%: ' . $use{$device} . ']';
+#
+#  and add or remove any of the following:
+#  $size{$device} is the total size of the drive
+#  $used{$device} is the total amount of used space
+#  $avail{$device} is the amount of available space
+#  $use{$device} is the percentage of space used
+#  $mount{$device} is the mount point
+#
+#  Next version, if I ever get around to making one, will have an easier system of changing the 
+#  way the statusbar item looks.
+#
+#  There's a command defined, /dfupdate, which will instantly update the statusbar item. If you
+#  want this information printed in the statuswindow, use /exec df -h in any window :).

+# OPTIONS
+######
+#
+#  The irssi command /set can be used to change these settings (more to follow):
+#  * df_refresh_time (default: 60)
+#      The number of seconds between updates.
+#
+###
+#########
+# TODO
+###
+#
+#  - Add format support so the display is more easily customizable.
+#  - Add a list of devices to display.
+#  - Add a setting that'll let user define the switches to pass to df?
