The pages CMS provide a command for those that would prefer to use PO files instead of the admin inteface to translate the pages content.
To export all the content from the published page into PO files you can execute this Django command:
$ python manage.py pages_export_po <path>
The files a created in the poexport directory if no path is provided.
After the translation is done, you can import back the changes with another command:
$ python manage.py pages_import_po <path>
