# From Bazel's perspective, this is almost equivalent to always specifying
# --extra_toolchains on every bazel <...> command-line invocation. It also
# means there is no way to disable the toolchain with the command line. This is
# useful if you find bazel-hermetic-cc useful enough to compile for all of your
# targets and tools.
#
# With BAZEL_DO_NOT_DETECT_CPP_TOOLCHAIN=1 Bazel stops detecting the default
# host toolchain. Configuring toolchains is complicated enough, and the
# auto-detection (read: fallback to non-hermetic toolchain) is a footgun best
# avoided. This option is not documented in bazel, so may break. If you intend
# to use the hermetic toolchain exclusively, it won't hurt.
