I'm using sx.translations + five in order to achive this
programatically. In order to use i18n from five, read this:
http://codespeak.net/z3/five/i18n.html
Then install sx.translations from here:
http://www.simplistix.co.uk/software/zope/sx.translations
Please note that the product self do not compile po files into mo you
have to compile it either manually or apply my patch:
https://secure.simplistix.co.uk/support/issue310
I did also some functions to be able to translate messages
programatically. Please note that I'm using zope 2.8, so, I don't know
if it will work with 2.10.x. Please also note that I'm using a request
variable called 'lang' to set the source language. If this variable
isn't set, then the browser language will be assumed.
Best regards
Josef
