keys or mouse buttons, using a configuration file.  It's independent of the
window manager and can capture all keyboard keys (ex: Power, Wake...).  It
optionally supports a Guile-based configuration file layout, which enables you
to access all XBindKeys internals, so you can have key combinations, double
clicks or timed double clicks take actions.  Also all functions that work in
Guile will work for XBindKeys.")

It was primarily designed for clipmenu, to avoid polling for new selections.

@command{clipnotify} doesn't try to print anything about the contents of the
selection, it just exits when it changes.  This is intentional -- X11's
selection API is verging on the insane, and there are plenty of others who
have already lost their sanity to bring us xclip/xsel/etc.  Use one of those
tools to complement clipnotify.")
