+# Don't create bazel-* symlinks in the WORKSPACE directory.
+# These require .gitignore and may scare users. Also, it's a workaround for
+# https://github.com/bazelbuild/rules_typescript/issues/12 which affects the common case of
+# having `tsconfig.json` in the WORKSPACE directory. Instead, you should run
+# `bazel info output_base` to find out where the outputs went.

+# Show which actions are run under workers,
+# and print all the actions running in parallel.
+# Helps to demonstrate that bazel uses all the cores on the machine.
