If the directory does not exist, it is created. Use the suffix provided for the base directory, and default to '.distlib' if it isn't provided. On Windows, if LOCALAPPDATA is defined in the environment, then it is assumed to be a directory, and will be the parent directory of the result. On POSIX, and on Windows if LOCALAPPDATA is not defined, the user's home directory - using os.expanduser('~') - will be the parent directory of the result. The result is just the directory '.distlib' in the parent directory as determined above, or with the name specified with ``suffix``.
