# Args:
#
#   - icu_base_packages: same as `base_packages` from assembly_input_bundle,
#     but needs ICU adaptation.
#   - all other args are the same as in `assembly_input_bundle`
#
# Refer to icu_source_set.gni for detailed comments on some constructs below,
# the ideas of which are commonly reused in all icu_* templates.
