I think we're ready for someone to look at the POT and tell us whether it's
clean enough to translate.

As mentioned before, the Esperanto translation isn't Esperanto, it's a faked
translation using Ned Batchelder's "poxx" technique.[1] If you're running
pybabel-extract, you'll need 'polib' (easy_install polib).

I overhauled pybabel-extract so that it creates a proper PO header, without
all the dummy variables. (It seems that Babel was designed to be used
primarily via 'setuptools'; if you use the command-line approach, you get
fewer options.)

en_CA is the default language; fr_CA can be selected via 'Preferences'.
