"""
This will generate the .pot and .mo files for the application domain and
languages defined below.

The .po and .mo files are placed as per convention in

"appfolder/locale/lang/LC_MESSAGES"

The .pot file is placed in the locale folder.

This script or something similar should be added to your build process.

The actual translation work is normally done using a tool like poEdit or
similar, it allows you to generate a particular language catalog from the .pot
file or to use the .pot to merge new translations into an existing language
catalog.
