+:mod:`tabnanny` --- Detection of ambiguous indentation
+======================================================
+
+.. module:: tabnanny
+ :synopsis: Tool for detecting white space related problems in Python source files in a
+ directory tree.
+.. moduleauthor:: Tim Peters <tim_one@users.sourceforge.net>
+.. sectionauthor:: Peter Funk <pf@artcom-gmbh.de>
+
+.. rudimentary documentation based on module comments
+
+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 :func:`check`
+described below.
+
+.. warning::
+
+ The API provided by this module is likely to change in future releases; such
+ changes may not be backward compatible.
+
+
+.. function:: check(file_or_dir)
+
+ 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 :file:`.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.
+
+
+.. data:: verbose
+
+ Flag indicating whether to print verbose messages. This is incremented by the
+ ``-v`` option if called as a script.
+
+
+.. data:: filename_only
+
+ 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.
+
+
+.. exception:: NannyNag
+
+ Raised by :func:`tokeneater` if detecting an ambiguous indent. Captured and
+ handled in :func:`check`.
+
+
+.. function:: tokeneater(type, token, start, end, line)
+
+ This function is used by :func:`check` as a callback parameter to the function
+ :func:`tokenize.tokenize`.
+
+.. XXX document errprint, format_witnesses, Whitespace, check_equal, indents,
+ reset_globals

+ Module :mod:`tokenize`
+ Lexical scanner for Python source code.
