[vox-tech] "bring to front" X-window command

[Jonathan Stickel]

Is there a command I can run from commandline, say from an xterm 
(actually konsole), to select a certain window in an X-session (actually 
KDE) and push it to the top?  I'm doing some scripting and have a 
command which essentially seems to do a screen capture.  I want it to 
capture the contents of a certain window, but that window must be on 
top, of course, not hiding behind another window.

Thanks,
Jonathan
