The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. If the file pointed by the symlink doesn't exist, an exception will be added in the list of errors raised in an Error exception at the end of the copy process. You can set the optional ignore_dangling_symlinks flag to true if you want to silence this exception. Notice that this has no effect on platforms that don't support os.symlink. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied. It returns a list of names relative to the `src` directory that should not be copied. The optional copy_function argument is a callable that will be used to copy each file. It will be called with the source path and the destination path as arguments. By default, copy2() is used, but any function that supports the same signature (like copy()) can be used. i N( u osu listdiru Noneu setu makedirsu pathu joinu islinku readlinku symlinku existsu isdiru copytreeu Erroru extendu argsu EnvironmentErroru appendu stru copystatu OSErroru WindowsErroru isinstance( u srcu dstu symlinksu ignoreu copy_functionu ignore_dangling_symlinksu namesu ignored_namesu errorsu nameu srcnameu dstnameu linktou erru why( ( u= /tmp/pip-zej_zi-build/pip/_vendor/distlib/_backport/shutil.pyu copytree� sD $ &3/c $ C s� | r d d � } n | d k r0 d d � } n y% t j j | � rT t d � � n Wn2 t k r� | t j j | t j � � d SYn Xg } y t j | � } Wn. t j k r� | t j | t j � � Yn Xx� | D]� } t j j | | � } y t j | � j } Wn t j k r)d } Yn Xt j | � rLt | | | � q� y t j | � Wq� t j k r�| t j | t j � � Yq� Xq� Wy t j | � Wn. t j k r�| t j | t j � � Yn Xd S( u� Recursively delete a directory tree. If ignore_errors is set, errors are ignored; otherwise, if onerror is set, it is called to handle the error with arguments (func, path, exc_info) where func is os.listdir, os.remove, or os.rmdir; path is the argument to that function that caused it to fail; and exc_info is a tuple returned by sys.exc_info().

This is similar to the Unix "mv" command. If the destination is a directory or a symlink to a directory, the source is moved inside the directory. The destination path must not already exist. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on our current filesystem, then rename() is used. Otherwise, src is copied to the destination and then removed. A lot more could be done here... A look at a mv.c shows a lot of the issues this implementation glosses over.
