VIM IS... NOT						*design-not*

- Vim is not a shell or an Operating System.  You will not be able to run a
  shell inside Vim or use it to control a debugger.  This should work the
  other way around: Use Vim as a component from a shell or in an IDE.
  A satirical way to say this: "Unlike Emacs, Vim does not attempt to include
  everything but the kitchen sink, but some people say that you can clean one
  with it.  ;-)"
- Vim is not a fancy GUI editor that tries to look nice at the cost of
  being less consistent over all platforms.  But functional GUI features are
  welcomed.
