EnvBuildera�
    This class exists to allow virtual environment creation to be
    customized. The constructor parameters determine the builder's
    behaviour when called upon to create a virtual environment.

    By default, the builder makes the system (global) site-packages dir
    *un*available to the created environment.

    If invoked using the Python -m option, the default is to use copying
    on Windows platforms but symlinks elsewhere. If instantiated some
    other way, the default is to *not* use symlinks.

    :param system_site_packages: If True, the system (global) site-packages
                                 dir is available to created environments.
    :param clear: If True, delete the contents of the environment directory
if
                  it already exists, before environment creation.
    :param symlinks: If True, attempt to symlink rather than copy files
into
                     virtual environment.
    :param upgrade: If True, upgrade an existing virtual environment.
    :param with_pip: If True, ensure pip is installed in the virtual
                     environment
    :param prompt: Alternative terminal prefix for the environment.

        Set up scripts into the created environment from a directory.

        This method installs the default scripts into the environment
        being created. You can prevent the default installation by
overriding
        this method if you really need to, or if you need to specify
        a different location for the scripts to install. By default, the
        'scripts' directory in the venv package is used as the
source of
        scripts to install.
