Foilding vimscripts

[Preben Randhol]

Hi

This is probably a stupid question, but does anybody have a setup for
folding vimscripts? In most other languages the folding are either
included or one can download scripts from vim.org. However, I cannot
find any script for folding vimscripts.

I'm interested mostly in folding:

        function! boo()
                ....
        endfunction

Thanks in advance

Preben
