+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.
+
+\strong{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 set to true 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}
