tabnanny -- Detection of ambiguous indentation
For the time being this module is intended to be called as a script.
However it is possible to import it into an IDE and use the function
check() described below.
Warning: The API provided by this module is likely to change in future
releases; such changes may not be backward compatible.

If file_or_dir is a directory and not a symbolic link, then recursively
descend the directory tree named by file_or_dir, checking all .py files
along the way. If file_or_dir is an ordinary Python source file, it is
checked for whitespace related problems. The diagnostic messages are
written to standard output using the print statement.
