[bizygecf] Swapping CapsLock and Control

Using the GUI to swap Caps Lock and Control in GNOME 2 caused the file ~/.gconf/desktop/gnome/peripherals/keyboard/kbd/%gconf.xml to be created with the following contents:

<?xml version="1.0"?>
<gconf>
 <entry name="options" mtime="1329506552" type="list" ltype="string">
  <li type="string">
   <stringvalue>ctrl ctrl:swapcaps</stringvalue>
  </li>
 </entry>
</gconf>

This gives enough rope to discover how to do or undo it at the command line:
gconftool-2 --type=list --list-type=string --set /desktop/gnome/peripherals/keyboard/kbd/options "[ctrl"$'\t'"ctrl:swapcaps]"
gconftool-2 -u /desktop/gnome/peripherals/keyboard/kbd/options

Note that the $'\t' is the weird bash shell backslash escape sequence for a tab.
