Description

What problem does this solve?

We have many users of this CLI from all over the world, so it may be useful to provide translations for our error messages? Possibly ones that default to the language set by the user's environment variables? That would likely make the CLI easier to use for them.

Solution description

This is more-so a discussion and idea generation issue, rather than an explicit feature spec.

Research direction
This issue is a discussion for adding i18n support to urfave/cli. It lacks a concrete specification. To proceed, one should explore how other Go CLI libraries implement i18n, consider using environment variables (e.g., LANG, LC MESSAGES) to detect user locale, and propose a design for integrating translations into error messages. The maintainers may need to weigh in on the preferred approach before implementation.
