Arguably is a minimalist Rust library for parsing command line arguments. Its features include:
Long-form boolean flags with single-character shortcuts: --flag, -f.
Long-form string-valued options with single-character shortcuts: --option <arg>, -o <arg>.
Condensed short-form options: -abc <arg> <arg>.
Automatic --help and --version flags.
Support for multivalued options.
Support for git-style command interfaces with arbitrarily-nested commands.
