# Locale load_path and Locale loading support.
#
# To use this include the Globalize::LoadPath::I18n module to I18n like this:
#
# I18n.send :include, Globalize::LoadPath::I18n
#
# Clients can add load_paths using:
#
# I18n.load_path.add load_path, 'rb', 'yml' # pass any number of extensions like this
# I18n.load_path << 'path/to/dir' # usage without an extension, defaults to 'yml'
#
# And load locale data using either of:
#
# I18n.load_locales 'en-US', 'de-DE'
# I18n.load_locale 'en-US'
#
# This will lookup all files named like:
#
# 'path/to/dir/all.yml'
# 'path/to/dir/en-US.yml'
# 'path/to/dir/en-US/*.yml'
#
# The filenames will be passed to I18n.load_translations which delegates to
# the backend. So the actual behaviour depends on the implementation of the
# backend. I18n::Backend::Simple will be able to read YAML and plain Ruby
# files. See the documentation for I18n.load_translations for details.
