... but I am "within the castle", I'm sitting running a script on the
win2k system and I can't see how to run xwinclip there because it
won't give me permission to display on the terminal that I'm already
using.
It's of little use to be able to allow xwinclip to run on the win2k
system by executing something on the Linux system. One wants a means
to do it from the X startup script.
