\begin{funcdesc}{rmtree}{path\optional{, ignore_errors\optional{, onerror}}}
\index{directory!deleting}
Delete an entire directory tree. If \var{ignore_errors} is true,
- errors will be ignored; if false or omitted, errors are handled by
- calling a handler specified by \var{onerror} or raise an exception.
+ errors resulting from failed removals will be ignored; if false or
+ omitted, such errors are handled by calling a handler specified by
+ \var{onerror} or, if that is omitted, they raise an exception.
If \var{onerror} is provided, it must be a callable that accepts
three parameters: \var{function}, \var{path}, and \var{excinfo}.
