logging-to-stderr

name	logging-to-stderr
description	Set up logging with verbosity levels via --verbose flags, sending log output to stderr. Use when adding logging to a CLI tool or script.

Set up logging so each additional --verbose flag increases the log level. -v is an alias for --verbose.

All log messages go to stderr, not stdout.

Exception: Chrome extensions must log to stdout. Chrome treats stderr output as an extension failure, so redirect logging to stdout when working in a Chrome extension context.
