# Defines a renamed binary based on grand_unified_binary.
#
# GUB is a single binary that merges together multiple Go programs.
# The entry point to the combined program can identify which sub-program the
# caller intends to run based on the filename of the invocation (`argv[0]`).
#
# This template offers dependents a renamed grand_unified_binary binary.
#
# Parameters
#
#   output_name (optional)
#     The renamed binary's name.
#     Type: string
#     Default: target_name
#
#   testonly
#   visibility
