[Vimoutliner] How do you use _exe_ ?

[Mark S.]

Hello!

I've read through the vo help file. I appreciated the fact that its short 
enough to read in a half hour.  The file talks about the _exe_ feature. 
Unfortunately, it doesn't say how to *use* this feature -- just how to set it 
up. Once you have your head line set up, then what?

Also, the last line in the section on executable lines says this:

  To enable this behavior, insert the following code into your  
  $HOME/.vimoutlinerrc file:

Unfortunately, that's where it ends -- the secret codex is missing. So I have 
no clue what I'm supposed to put in .vimoutlinerrc or even if I need to.

Thanks!
Mark
