python gettext example?

Hello,
Are there an examples of Python programs using gettext. I am trying to work 
up a simple example so I can internationalize an open source Python project I 
have. 

I think I know how to prepare the source code prepared but I don't understand 
how it all works together.

I put this at the top of files:

from gettext import gettext as _
from gettext import bindtextdomain, textdomain
from os import sep
from locale import setlocale, LC_ALL

LOCALE_PREFIX = "%susr" % (sep)
LOCALE_DIR = "%s%sshare%slocale" % ( LOCALE_PREFIX, sep, sep )
PACKAGE = "deodas"

setlocale( LC_ALL )
bindtextdomain( PACKAGE, LOCALE_DIR )
textdomain( PACKAGE )

# in the code
string = _( u'A sentance to translate.' )

The source code looks like 
module/__init__.py 
module/etc...
po/POTFILES.in
po/es.po
po/es.mo

I used 
	pygettext filename  &
	msgfmt.py es.po 
to pull out the strings and make the translation catalog.  

How do I run the program using a translation file?
