Bazel Features

Use this to determine the availability of a Bazel feature in your ruleset. It works under the hood by comparing the Bazel version against a known range in which the feature is available. Example usage:

load("@bazel_features//:features.bzl", "bazel_features")
if bazel_features.toolchains.has_optional_toolchains:
    # Do something

The features.bzl file contains the list of features.
