Add support for using single files

[hrw]

I got strings.xml dialog.xml in EN and PL languages for one Android application. Checked your tool as a way to get it done using gettext based tools but I fail to get it working:

14:57 hrw@puchatek:ussdchecker$ ls -R
.:
res

./res:
values values-pl

./res/values:
dialog.xml strings.xml

./res/values-pl:
dialog.xml strings.xml
14:57 hrw@puchatek:ussdchecker$ a2po --android $PWD/res --gettext . init
usage: a2po [-h] [--version] {import,init,export} ...
a2po: error: argument command: invalid choice: '/home/hrw/HDD/devel/devices/android/t\xc5\x82umaczenia/ussdchecker/res' (choose from 'import', 'init', 'export')

babel 0.9.6, other deps are installed too.
Ubuntu 11.10 'oneiric'

You need to specify the command first:

a2po init [args]
