+# 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.
