Command Line Parser Library
summary
A composable command-line parser called Clara is extracted from Catch and rewritten for C++11 so CLI code composes instead of duplicating. Each option is a small parser that lexes into a token stream and returns remaining tokens and status (error short-circuiting). Parsers combine with a pipe operator to build a single parser that exposes help, integrates with Catch2’s main or user main, and already drives Catch’s CLI, proving the design works in practice.
