INTRO:
  In a new bottow window, display help doc strings of word under the cursor
by scanning the modules in the current file as you press key.

It requier Vim compiled with "+python" and MUST set iskeyword+=.

It work well in my box in Win2000 and Vim6.3. If it work in other  platform
or other version of Vim, let me know.

I think it better than the call tips of idle and pywin:) if you like it ,let
me know.
