# Experimental support for using Gettext po files to store translations.
#
# To use this you can simply include the module to the Simple backend - or
# whatever other backend you are using.
#
# I18n::Backend::Simple.include(I18n::Backend::Gettext)
#
# Now you should be able to include your Gettext translation (*.po) files to
# the I18n.load_path so they're loaded to the backend and you can use them as
# usual:
#
# I18n.load_path += Dir["path/to/locales/*.po"]
#
# Following the Gettext convention this implementation expects that your
# translation files are named by their locales. E.g. the file en.po would
# contain the translations for the English locale.
