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.
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.
Flag indicating whether to print verbose messages.
This is incremented by the -v option if called as a script.
Flag indicating whether to print only the filenames of files
containing whitespace related problems. This is set to true by the
-q option if called as a script.
Raised by tokeneater() if detecting an ambiguous indent.
Captured and handled in check().
