Notifier is just a small application which creates a popup shell which
pops up and highlights it's most recent input whenever it gets
anything on stdin.

This would be unexciting (but possibly useful) without the addition of
stderrNotifier(), a subroutine which should be called from your
main().  It spawns a notifier process and then pipes stderr output
from the current process to the notifier.  Anything subsequently
written to stderr will cause the notifier to pop up and scroll to the
most recent message.  The notifier keeps a scrolling list of all the
input it has received and even stays around after the program has
exited (only if it is already up, thus catching the bomb message if
there was one).

Small, simple and immensely useful (in my estimation).  I'm surprised
nobody thought of this before.

Arguments:
 -[no]bell		Enable or disable bell on popup (default on).
 -[no]center		Enable or disable automatic placement under mouse. (on)

If the label of the title widget is not specified then it defaults to
the name of the application.  So '-name foo' has the immediate
consequence of changing the title label to 'foo' unless this is
overridden in the app-defaults.

Placement of the window (when -nocenter) is used is via the geometry
of the "shell" widget.  So a regular -geometry spec doesn't buy you
anything.  Use -xrm "*shell.geometry: ..." instead.
