This module is under development.

Here is an example session:

------------------

Trouble shoot when ox sever window (xterm) does not show up.

1. On knoppix/math, start M2 with 
       openxm M2

2. If you suspect the locale is not properly set,
   add 
      XTerm*locale:false
   to .Xdefaults or .Xresources and load them by
      xrdb .Xdefaults

   "xterm" crashes if the locale is not properly set.

3. asir_1, asir_2, ... cannot be used as polynomial variabes.
