-"""Runfiles lookup library for Bazel-built Python binaries and tests.
-
-Usage:
-
-from bazel_tools.tools.runfiles import runfiles
-
-r = runfiles.Create()
-with open(r.Rlocation("io_bazel/foo/bar.txt"), "r") as f:
-  contents = f.readlines()
-
-The code above creates a manifest- or directory-based implementations based on
-the environment variables in os.environ. See `Create()` for more info.
-
-If you want to explicitly create a manifest- or directory-based
-implementations, you can do so as follows:
-
-  r1 = runfiles.CreateManifestBased("path/to/foo.runfiles_manifest")
-
-  r2 = runfiles.CreateDirectoryBased("path/to/foo.runfiles/")
-
-If you want to start subprocesses that also need runfiles, you need to set the
-right environment variables for them:
-
-  import subprocess
-  from bazel_tools.tools.runfiles import runfiles
-
-  r = runfiles.Create()
-  env = {}
-  ...
-  env.update(r.EnvVars())
-  p = subprocess.Popen([r.Rlocation("path/to/binary")], env, ...)
