usage: fixup_pubsub_v1_keywords.py [-h] -d INPUT_DIR -o OUTPUT_DIR

Fix up source that uses the pubsub client library. The existing sources are NOT overwritten but
are copied to output_dir with changes made. Note: This tool operates at a best-effort level at
converting positional parameters in client method calls to keyword based parameters. Cases where
it WILL FAIL include A) * or ** expansion in a method call. B) Calls via function or method alias
(includes free function calls) C) Indirect or dispatched calls (e.g. the method is looked up
dynamically) These all constitute false negatives. The tool will also detect false positives when
an API method shares a name with another method.
