# This file creates the |locales| which is the set of current
# locales based on the current platform. Locales in this list are formated
# based on what .pak files expect.
# The |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:
# - |android_apk_locales| subset for Android based apk builds
# - |android_bundle_locales_as_resources| locales formatted for XML output names
# - |locales_as_mac_outputs| formated for mac output bundles
# - |ios_packed_locales| subset for iOS
# - |ios_packed_locales_as_mac_outputs| subset for iOS output

# Android doesn't ship all locales in order to save space (but webview does).
