OK, I give up, what's notify-send supposed to do? I can't seem
to find any docs on notify-send.  There's no manpage (at least
not on gentoo). Running this does nothing:
  
 $ notify-send summary "this is the body"

The output of notify-send --help is pretty cryptic, and
googling it didn't really find aything very instructive.
