This is really weird:

   ~% echo exit 0 > zero
   ~% echo exit 1 > one
   ~% echo exit 2 > two
   ~% chmod +x zero one two
   ~% ./zero ; echo $?
   0
   ~% ./one  ; echo $?
   1
   ~% ./two  ; echo $?
   2
   ~% python
   Python 2.1.3 (#1, Sep  7 2002, 15:29:56)

   >>> import os
   >>> os.system("/home/matej/one")
   256
   >>> os.system("/home/matej/two")
   512
   >>> os.system("/home/matej/zero")
   0
   >>>
   ~% bogofilter < relson
   ~% echo $?
   1
   ~% 

(relson is obviously your previous mail). Does it mean, that
I should divide returned value by 256 or that I should make some
bitwise masking (xoring?)?

   Thanks for help,

The main idea of the pope's asking for forgivness was not to be
afraid of the truth. DO NOT BE AFRAID OF TRUTH! We have to have
faith in the God's governing power to be able not to be afraid.
