# coding: utf-8
#Make a 'localization' for Date, DateTime and Time.
#
#This is not using locale, but if you use locale, it is detected and locale sensitive.
#
#The output is in iso-8859-1, other encodings can be set with Date_locale.set_target_encoding.
#
require 'date'
#
#Adaption for a localized Date-class
#
#Solution based on discussion at ruby-forum.de

#
module Date_locale
#Constant/Hash with the supported languages.
#
#Initial definitions are taken from localization_simplified.
#
#Changes:
#* added de_at
#* adapted :pt to pt_br (original :pt was French).
