Packages and the import mechanism in general are still left
undocumented.

macros.

of three macros, one which replaces some of the current conventions used in
the module sections:

  \declaremodule:  Requires two parameters: module type (standard, builtin,
	extension), and the module name.  An optional parameter should be
	given as the basis for the module's "key" used for linking to or
	referencing the section.  The "key" should only be given if the
	module's name contains underscores, and should be the name with the
	underscore's stripped.  This should be the first thing after the
	\section used to introduce the module.

  \modulesynopsis:  Requires a single parameter: a short, one-liner
	description of the module that can be used as part of the chapter
	introduction.  This should probably be placed just after the
	\declaremodule, but may be placed anywhere in the same section.

  \localmoduletable:  No parameters.  If a .syn file exists for the current
	chapter (or for the entire document in howto docs), a synopsistable
	is created with the contents loaded from the .syn file.

Some re-organization due to module synopsis support.

Some \def's changed to \newcommand's.

\chapter:  Extended, ensures that a pending module synopsis is written out
	and then closes the .syn file for the preceeding chapter.

posix_error_with_filename(): New function which calls
PyErr_SetFromErrnoWithFilename()

The following methods have been changed to call
posix_error_with_filename():

    posix_1str()
    posix_strint()
    posix_strintint()
    posix_do_stat()
    posix_mkdir()
    posix_utime()
    posix_readlink()
    posix_open()

INITFUNC(): os.error (nee PosixError) is PyExc_OSError

was used so it's reflected in the IOError.  Call
PyErr_SetFromErrnoWithFilename().

an exception from errno, with a supplied filename (primarily used by
IOError and OSError).  If class exceptions are used then the exception
is instantiated with a 3-tuple: (errno, strerror, filename).  For
backwards compatibility reasons, if string exceptions are used,
filename is ignored.

PyErr_SetFromErrno(): Implement in terms of
PyErr_SetFromErrnoWithFilename().

involve a filesystem path.  To that end:

- Changed IOError to EnvironmentError and added a hack which checks
  for arg of len 3.  When constructed with a 3-tuple, the third item
  is the filename and this is squirreled away in the `filename'
  attribute.   However, for in-place unpacking backwards
  compatibility, self.args still only gets the first two items.  Added
  a __str__() which prints the filename if it is given.

- IOError now inherits from EnvironmentError

- New class OSError which also inherits from EnvironmentError and is
  used by the posix module.

OSError.  The EnvironmentError serves primarily as the (common
implementation) base class for IOError and OSError.  OSError is used
by posixmodule.c

Also added tuple definition of EnvironmentError when using string
based exceptions.

New function: PyErr_SetFromErrnoWithFilename(PyObject* char*)

Change the argument name for quote() and quote_plus() to safe (which
matches the implementation).

Add doc for the *new* function urlencode().

Fix the implementation of quote_plus().  (It wouldn't treat '+' in the
original data right.)

Add urlencode(dict) which is handy to create the data for sending a
POST request with urlopen().
