[Plone-i18n] Setup of translation environment

[<ad...@ad...>]

Hi,

Some time ago I started translating Plone to my language. This was  
with version 2.1. I also installed i18ndude and some tools mentioned  
in http://plone.org/development/teams/i18n/rebuild-pots

After translating a whole lot of strings version 2.5 came out and now  
I wanted to update, but I have since forgot how to do it. The how to  
in http://plone.org/development/teams/i18n/rebuild-pots doesn't help  
much because
a) I'm not running Windows; Mac OS X is my work environment
b) I'm not hosting on the computer I'm translating on; debian is my  
hosting environment.

My quesion is: How do I set up the environment correctly given my  
circumstances? How would setenv.sh look like? What other things do I  
need to be aware of? Do I need to have plone set up on my laptop to  
be able to check my translations?
