# Creates an action to call the repack_locales script.
#
# The GYP version generates the locales in the "gen" directory and then copies
# it to the root build directory. This isn't easy to express in a GN copy
# rule since the files on Mac have a complex structure. So we generate the
# files into the final place and skip the "gen" directory.
#
# This template uses GN's looping constructs to avoid the complex call to
# chrome/tools/build/repack_locales.py which wraps the repack commands in the
# GYP build.
#
# Arguments

#       List of locale names to use as inputs.
#

#       input names. Mac uses different names in some cases.
