\modulesynopsis{Tool for detecting white space related problems
in Python source files in a directory tree.}

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
\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.}
\begin{funcdesc}{check}{file_or_dir}
If \var{file_or_dir} is a directory and not a symbolic link, then
recursively descend the directory tree named by \var{file_or_dir},
checking all \file{.py} files along the way. If \var{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.
\end{funcdesc}
\begin{datadesc}{verbose}
Flag indicating whether to print verbose messages.
This is incremented by the \code{-v} option if called as a script.
\end{datadesc}
\begin{datadesc}{filename_only}
Flag indicating whether to print only the filenames of files
containing whitespace related problems. This is set to true by the
\code{-q} option if called as a script.
\end{datadesc}
\begin{excdesc}{NannyNag}
Raised by \function{tokeneater()} if detecting an ambiguous indent.
Captured and handled in \function{check()}.
\end{excdesc}
\begin{funcdesc}{tokeneater}{type, token, start, end, line}
This function is used by \function{check()} as a callback parameter to
the function \function{tokenize.tokenize()}.
\end{funcdesc}
