+
+  == 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 ==
+  You can style the buftabs with:
+
+  :style * .buftab { <CSS> }
+
+  and 
+
+  :style * .buftab_selected { <CSS> }
+
+  == 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.
