  == Usage ==
  When the script is loaded it hijacks the statusline to display a list of tabs,
  you can use the "buftabs" option to toggle it on or off.

  == Styling ==
  Use the BufTab and BufTabSelected highlight groups to style the buftabs.
  Make sure you've called the "loadplugins" command before using the highlight
  groups in your vimperatorrc.

  == Length ==
  You can set the max length of a title before it is cut off with the 
  buftabs_maxlength option. It is set to 25 by default.
