Hi,

as we build an international application we need a translation mechanism for ruby on rails. i did some research and found that gettext is supported best and has a nice documentation. GetText Documentation

good :
- translations are not stored in the database
- translation is done with _(’string’) - so it`s easy to implement
- gem install gettext
- there is an editor for editing the translations - poedit
- the catalog can be build from your _(’string’) entries in your model,controller and views

bad :
- po files need to be converted to mo files and then are useable from the system

trap :
- first add gettext to your application.rb and then do the rake tasks
