Overview

Three-layer option lookup: command line beats config file beats default.

Same precedence as puma's UserFileDefaultOptions, and for the same reason -- a config file is checked in and shared, a command line is what you type to override it right now. Kept as three separate hashes rather than one merged one so puma-plus --port 3000 still wins over a port 9292 in the file no matter which was read first.

#origin(key) ⇒ Object
