->For your enjoyment I have implemented a colorful clock.
-
-The clock has now been extended with some new facilities: a menu, an
-alarm and a gong. These may require some explanation beyond what's in
-the usage message.
-
-Menu
-----
-The right mouse button now pops up a menu that allows you to turn the
-seconds hand on or off and to switch the alarm off.
-
-Alarm
------
-
-The left and middle buttons set the alarm. When it is on, the alarm
-time is displayed as a time on a 24 hour clock in the bottom left
-corner. It is also indicated by two red triangles, corresponding to the
-little (hours) and big (minutes) hand. These hands can be moved around:
-the left mouse button moves the minutes hand, the middle button moves
-the hourds hand. Watch out for differences of twelve hours (always
-check the digital display); these can be corrected by dragging the hours
-hand once around the dial.
-
-When the alarm goes off, two things happen: a shell command specified on
-the command line with the -a option is executed (in the background), and
-the clock's colors change every two seconds, for five minutes. You can
-also turn the alarm off by using the menu accessible through the right
-mouse button.
-
-There is no default command for the -a option; if it is not specified,
-only the changing of the colors happens. If you have an 8 ohm speaker
-connected to the audio output of your Personal Iris, a suitable command
-would be:
-
- mclock -a '/ufs/guido/bin/sgi/play /ufs/guido/lib/sounds/alarm'
-
-Gong
-----
-
-Some people like a clock that makes noises every hour, or even more
-often. This is supported by the -g and -G options. With -g you specify
-a shell command to be executed to sound the gong; with -G you can
-specify the interval between gong calls, in seconds (default is one hour).
-The shell command is executed in the background. It is given two
-arguments: the hours (on a 24 hour clock!) and the minutes. The
-executable Python script /ufs/guido/bin/sgi/chime is a suitable example.
-Again, this only works if you have installed a speaker (I bet 8 ohm
-speakers are going to be in demand!)
