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.
