# This file creates |platform_pak_locales| which is the set of packed locales
# based on the current platform. Locales in this list are formatted based on
# what .pak files expect. The |platform_pak_locales| variable *may* contain
# pseudolocales, depending on the |enable_pseudolocales| flag.
# If you specifically want to have the locales variable with or without
# pseudolocales, then use |locales_with_pseudolocales| or
# |locales_without_pseudolocales|.

# The following additional platform specific lists are created:
# - |extended_locales| list of locales not shipped on desktop builds
# - |android_bundle_locales_as_resources| locales formatted for XML output names
# - |locales_as_apple_outputs| formatted for mac output bundles
