+Values: A map (format specified below).
+Default: {}
+
+Use this option if you have new filetypes you want the script to handle, or if
+you want to override the default delimiters of a filetype.
+
+Example: >
+    let g:NERDCustomDelimiters = {
+        \ 'ruby': { 'left': '#', 'leftAlt': 'FOO', 'rightAlt': 'BAR' },
+        \ 'grondle': { 'left': '{{', 'right': '}}' }
+    \ }
+<
+
+Here we override the delimiter settings for ruby and add FOO/BAR as alternative
+delimiters. We also add {{ and }} as delimiters for a new filetype called
+'grondle'.

+2.3.0
+    - remove all filetypes which have a &commentstring in the standard vim
+      runtime for vim > 7.0 unless the script stores an alternate set of
+      delimiters
+    - make the script complain if the user doesnt have filetype plugins enabled
+    - use <leader> instead of comma to start the default mappings
+    - fix a couple of bugs with sexy comments - thanks to Tim Smart
+    - lots of refactoring
+
 2.2.2
     - remove the NERDShutup option and the message is suppresses, this makes
       the plugin silently rely on &commentstring for unknown filetypes.
