Issue #9960 has been updated by Andrew Vit.


@nobu "customarily" means "commonly" (English noun "a custom" vs. adjective "custom": *a traditional and widely accepted way of behaving or doing something that is specific to a particular society, place, or time*)

It is true that most often -v means --verbose and -V means --version but it's not consistent, and not sure it's worth changing now.

----------------------------------------
Feature #9960: Add support for GNU --long options
https://bugs.ruby-lang.org/issues/9960#change-47310

* Author: Jari Aalto
* Status: Feedback
* Priority: Low
* Assignee: 
* Category: 
* Target version: 
----------------------------------------
Please consider adding GNU --long option equivalents. Notes:

* Prefer uppercase "V" for version, as small "v" is customarily user for --verbose.
* Change word "switches" into more commonly used "options" word in USAGE line.
