# Calls the remoting_localize script with a jinja2 template.
#
# Arguments
#
#   sources (required)
#     List of jinja2 files to load. This is the template.
#
#   locales (required)
#     List of locales.
#
#   locale_dir (optional)
#
#   defines (optional)
#     List of defines to pass to script.
#     Example: defines = [ "FOO_HOST_PATH=bar" ]
#
#   variables (optional)
#     List of variables to pass to script.
#
#   output (optiona)
#     Substitution pattern for the output. Defaults to a file in the target
#     gen dir with the extension stripped (normally the extension is ".jinja2"
#     which then leaves the non-tempaltized file name).
#   TODO(brettw) Need locale_output. This is a per-locale output file.
#
#   encoding (optional)
#     String.
#
#   deps (optional)
#   visibility (optional)
