Translate Gnome 3.4 for Ubuntu 12.04

[Khoem Sokhem <khoemsokhem khmeros info>]

Hello All,

my team plan to start translating Gnome 3.4 for the release of Ubuntu 
12.04 in to Khmer (the official language of Cambodia).

I have looked at: http://l10n.gnome.org/languages/km/gnome-3-4/ui/ and 
saw that there is not translations for my language, So Can I download 
all files from that and doing the translations and then uploading the 
completed translations, Is that possible?

Thanks for your comments!

Regards,
Sokhem
