"""
Simple bot to check whether two pages with the same name on different language
'pedias have interwiki links to the same page on another language.
Call the script with 3 arguments:
python are-identical.py lang1 lang2 name
The script will either print "Yes" and return exit code 0,
or print "No" and return exit code 1,
or print "Both links are already present"
and return exit code 2,
or print "One links already present"
and return exit code 0.
It may raise exceptions on pages that disappeared or whatever. This is
a simple framework at least for the moment.
