# rs-sub-ninja.sh is a drop-in replacement for ninja that should be
# used in sub-builds when resultstore is enabled.
# This combines just rsproxy-wrap.sh and rsninja.sh.
# The reason for this is that each ninja invocation must be paired
# with its own rsproxy process; rsproxy was only designed for the
# single-invocation use case.
# If you need to inject other wrappers between rsproxy-wrap.sh
# and ninja, then compose your own command from these components.
