add multiple po files into one, the default.po

I'm trying to add a i18n support for a CakePH开发者_如何学JAVAP plugin. I have multiple *.pot files which I've edited/translated with poedit. The thing is that I'll like to merge all the files into one default.po file.

Does anyone know how can I do that in the most easy/smart way?

You use msgcat for that.
