# xwin_find [-v|-q] [timeout] window_name_regex
#
# Look for a window of the windows full name given by a awk regular
# expression, and print the windows xwindow ID.
#
# If a timeout is given (in seconds)continue to look for the windows ID
# for this amount of time before returning. (EG default a single search)
#
# If no such window is found output nothing, just exit
#
# OPTIONS
# -v verbose, print the full matching xwininfo line on stderr
# -q do not print windows ID on stdout
