# All of these arguments originate from the legacy features defined in Bazel's Java code:
#     https://github.com/bazelbuild/bazel/blob/master/src/main/java/com/google/devtools/build/lib/rules/cpp/CppActionConfigs.java

# This feature replaces the need for action configs to list legacy features
# in `implies` to produce a working toolchain. The full list is the set of
# features that are implied (enabled) by built-in action  config definitions.
# Note that some other legacy features are still hidden and enabled by default,
# and others exist that are NOT enabled at all by default. As args are built
# out, the `implies` entry should be removed and then moved into `args`.
