How can I divide i18n resources into several files?

Instead of putting all the i18n resources into a single mess开发者_开发百科age file, I want to divide them into several files. Anybody can kindly tell me how can I do that? because the documentation of Play doesn't give me any idea.

Use the Messages Module, really nice for this purpose.

You can't on Play. Anyway, why would you need to do that? Makes harder to find where the keys for I18N are. If it's for "visual" purposes, just use comments (##) to create sections in the file.
