Launch this script (after nxproxy has been installed into $PATH) and you
 will be able to evoke any local command through a

    nxproxy -C <-> nxproxy -S

 connection on DISPLAY=:8.

 This eases testing NX compression without using NX agent on the server
 side.

 How to use:

    # install nxproxy into $PATH, then...
    $ cd doc/examples/
    $ ./run-nxproxy2nxproxy-test
    $ export DISPLAY=:8
    $ xterm
