options:
  --version                     display the version of the virtualenv package and its location, then
                                exit
  --with-traceback              on failure also display the stacktrace internals of virtualenv
                                (default: False)
  --read-only-app-data          use app data folder in read-only mode (write operations will fail
                                with error) (default: False)
  --app-data APP_DATA           a data folder used as cache by the virtualenv (default:
                                /tmp/.cache/virtualenv)
  --reset-app-data              start with empty app data folder (default: False)
  --upgrade-embed-wheels        trigger a manual update of the embedded wheels (default: False)
  -h, --help                    show this help message and exit

verbosity:
  verbosity = verbose - quiet, default INFO, mapping => CRITICAL=0, ERROR=1, WARNING=2, INFO=3,
  DEBUG=4, NOTSET=5

  -v, --verbose                 increase verbosity (default: 2)
  -q, --quiet                   decrease verbosity (default: 0)

discovery:
  discover and provide a target interpreter

  --discovery {builtin}         interpreter discovery method (default: builtin)
  -p, --python py               interpreter based on what to create environment
                                (path/identifier/version-specifier) - by default use the interpreter
                                where the tool is installed - first found wins. Version specifiers
                                (e.g., >=3.12, ~=3.11.0, ==3.10) are also supported (default: [])

  --pip version                 version of pip to install as seed: embed, bundle, none or exact
