    The install command is the preferred way to globally install apps
    from python packages on your system. It creates an isolated virtual
    environment for the package, then ensures the package's apps are
    accessible on your $PATH. The package's manual pages installed in
    share/man/man[1-9] can be viewed with man on an operating system where
    it is available and the path in the environment variable `PIPX_MAN_DIR`
    (default: {paths.DEFAULT_PIPX_MAN_DIR}) is in the man search path
    ($MANPATH).

    The result: apps you can run from anywhere, located in packages
    you can cleanly upgrade or uninstall. Guaranteed to not have
    dependency version conflicts or interfere with your OS's python
    packages. 'sudo' is not required to do this.

    pipx install PACKAGE_SPEC ...
    pipx install --python PYTHON PACKAGE_SPEC
    pipx install VCS_URL
    pipx install ./LOCAL_PATH
    pipx install ZIP_FILE
    pipx install TAR_GZ_FILE

    The PACKAGE_SPEC argument is passed directly to `pip install`.

    Virtual Environments will be installed to `$PIPX_HOME/venvs`.
    The default pipx home location is {paths.DEFAULT_PIPX_HOME} and can
    be overridden by setting the environment variable `PIPX_HOME`.
    If the `--global` option is used, the default pipx home location
    instead is {paths.DEFAULT_PIPX_GLOBAL_HOME} and can be overridden
    by setting the environment variable `PIPX_GLOBAL_HOME`.

    The default app location is {paths.DEFAULT_PIPX_BIN_DIR} and can be
    overridden by setting the environment variable `PIPX_BIN_DIR`.
    If the `--global` option is used, the default app location instead
    is {paths.DEFAULT_PIPX_GLOBAL_BIN_DIR} and can be overridden by
    setting the environment variable `PIPX_GLOBAL_BIN_DIR`.

    The default manual pages location is {paths.DEFAULT_PIPX_MAN_DIR} and
    can be overridden by setting the environment variable `PIPX_MAN_DIR`.
    If the `--global` option is used, the default manual pages location
    instead is {paths.DEFAULT_PIPX_GLOBAL_MAN_DIR} and can be overridden
    by setting the environment variable `PIPX_GLOBAL_MAN_DIR`.

    The default python executable used to install a package is
    {DOC_DEFAULT_PYTHON} and can be overridden
    by setting the environment variable `PIPX_DEFAULT_PYTHON`.
