# Original Localization plugin for Rails can be found at:

# Slightly edited by Jean-Philippe Lang
|
||
|
|
# - added @@langs and modified self.define method to maintain an array of available
|
||
|
|
# langages with labels, eg. { 'en' => 'English, 'fr' => 'French }
|
||
|
|
# - modified self.generate_l10n_file method to retrieve already translated strings
