This does not check whether the target actually exists, only judge from the appearance. Returns true if any of the following conditions is true: * a path separator is found (either os.path.sep or os.path.altsep); * a dot is found (which represents the current directory).

If it is, returns the path. If false, check if the path is an archive file (such as a .whl). The function checks if the path is a file. If false, if the path has an @, it will treat it as a PEP 440 URL requirement and return the path. zODirectory %r is not installable.
