Set X11 Icon Title

[Thomas D. Dean]

I have an X11 application that monitors CPU thingee's.  This application 
is tailored to the Intel i7 3930K CPU.  It displays things like 
temperatures, voltages, CPU speed, etc.

When I iconize it, the icon displays the application name.

I want to display the CPU clock speed when it is iconized.  The 
application calculates the CPU speed and reads temperatures, voltages, 
etc. every second.

I have looked on the web, but, the number of hits is too large and I 
cannot think of a way to narrow the search.

Is there any way to do this?

If anyone is interested, it is GPL.
