C++ objects with constructors are probably not a good idea.

Writing C is hard; are there any alternatives?
----------------------------------------------
whole lot of difference between C and C++ -- so the strategy of building a new
Python type around a C structure (pointer) type will also work for C++ objects.
-For C++ libraries, you can look at `SIP
-<http://www.riverbankcomputing.co.uk/software/sip/>`_, `CXX
-<http://cxx.sourceforge.net/>`_, `Boost
-<http://www.boost.org/libs/python/doc/index.html>`_, `Weave
-<http://www.scipy.org/Weave>`_ or `SWIG <http://www.swig.org>`_
+For C++ libraries, see :ref:`c-wrapper-software`.
I added a module using the Setup file and the make fails; why?
stash of Python modules. This scheme's name is derived from the idea of a
"home" directory on Unix, since it's not unusual for a Unix user to make their
home directory have a layout similar to :file:`/usr/` or :file:`/usr/local/`.
-This scheme can be used by anyone, regardless of the operating system their
-installing for.
+This scheme can be used by anyone, regardless of the operating system they
+are installing for.
Installing a new module distribution is as simple as ::
provided on initialization and retrieval. Lines beginning with ``'#'`` or
``';'`` are ignored and may be used to provide comments.
+Configuration files may include comments, prefixed by specific characters (``#``
+and ``;``). Comments may appear on their own in an otherwise empty line, or may
+be entered in lines holding values or spection names. In the latter case, they
+need to be preceded by a whitespace character to be recognized as a comment.
+(For backwards compatibility, only ``;`` starts an inline comment, while ``#``
+does not.)
+
+On top of the core functionality, :class:`SafeConfigParser` supports
+interpolation. This means values can contain format strings which refer to
+other values in the same section, or values in a special ``DEFAULT`` section.
+Additional defaults can be provided on initialization.
+
For example::
[My Section]
.. versionadded:: 2.3
+.. exception:: Error
+
+ Base class for all other configparser exceptions.
+
+
.. exception:: NoSectionError
Exception raised when a specified section is not found.
.. method:: ConfigParser.get(section, option[, raw[, vars]])
- Get an *option* value for the named *section*. All the ``'%'`` interpolations
- are expanded in the return values, based on the defaults passed into the
- constructor, as well as the options *vars* provided, unless the *raw* argument
- is true.
+ Get an *option* value for the named *section*. If *vars* is provided, it
+ must be a dictionary. The *option* is looked up in *vars* (if provided),
+ *section*, and in *defaults* in that order.
+ All the ``'%'`` interpolations are expanded in the return values, unless the
+ *raw* argument is true. Values for interpolation keys are looked up in the
+ same manner as the option.
.. method:: ConfigParser.items(section[, raw[, vars]])
.. method:: HTMLParser.handle_decl(decl)
- Method called when an SGML declaration is read by the parser. The *decl*
- parameter will be the entire contents of the declaration inside the ``<!``...\
- ``>`` markup. It is intended to be overridden by a derived class; the base
- class implementation does nothing.
+ Method called when an SGML ``doctype`` declaration is read by the parser.
+ The *decl* parameter will be the entire contents of the declaration inside
+ the ``<!...>`` markup. It is intended to be overridden by a derived class;
+ the base class implementation does nothing.
+
+
+.. method:: HTMLParser.unknown_decl(data)
+
+ Method called when an unrecognized SGML declaration is read by the parser.
+ The *data* parameter will be the entire contents of the declaration inside
+ the ``<!...>`` markup. It is sometimes useful to be be overridden by a
+ derived class; the base class implementation throws an :exc:`HTMLParseError`.
.. method:: HTMLParser.handle_pi(data)

-.. function:: itertools.chain.from_iterable(iterable)
+.. classmethod:: chain.from_iterable(iterable)
Alternate constructor for :func:`chain`. Gets chained inputs from a
single iterable argument that is evaluated lazily. Equivalent to::

systems.

Having seen the mechanics behind the iterator protocol, it is easy to add
-iterator behavior to your classes. Define a :meth:`__iter__` method which
+iterator behavior to your classes. Define an :meth:`__iter__` method which

The change which will probably break the most code is tightening up the
arguments accepted by some methods. Some methods would take multiple arguments
and treat them as a tuple, particularly various list methods such as
-:meth:`.append` and :meth:`.insert`. In earlier versions of Python, if ``L`` is
+:meth:`append` and :meth:`insert`. In earlier versions of Python, if ``L`` is
a list, ``L.append( 1,2 )`` appends the tuple ``(1,2)`` to the list. In Python
2.0 this causes a :exc:`TypeError` exception to be raised, with the message:
'append requires exactly 1 argument; 2 given'. The fix is to simply add an
