# This shell-script is argument-compatible with xcrun(1) as invoked
# by xnu's Makefiles. Additionally, it supports caching tools
# in the local build directory. It is tightly coupled to exactly
# the queries that MakeInc.cmd makes, in exactly the order it makes
# them. ./tools/remote_build.sh invokes this indirectly in caching
# mode, so '$(XCRUN) -sdk foo -find bar' copies 'bar' from wherever
# it is on-disk into ./BUILD/BuildData, and returns that path to the
# caller. In '-u' mode on a remote build server, cache tools
# relative to the current build directory are returned without
# actually calling through to xcrun(1), since the remote build
# server may not even have Xcode installed.
