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.

some previously undocumented features.

exceptions:

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().

with a null movie (giving time to all active movies)
- Made the graphics world parameter to SetMovieGWorld optional.

open MPEG files, etc.

filename may be omitted.

before calling it.  This check was there when the objects were of the
same type *before* coercion, but not if they initially differed but
became the same *after* coercion.

slightly different way to test for the existence of unread.

(which is not very relevant when you're in the debugger :-).

according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions.  Also added a helper method lookupmodule().

Also:

- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.

onecmd(line) must return the value returned by emptyline() or
default(line).

you need to edit four files in order to add one section to the manual?)

fp.tell() -- that won't work on Windows.

(A patch for rfc822 is still needed for one case where it finds a bad
header line and wants to back up.)

 with LaTeX markup added, and some small rewrites to improve the prose.

to core dump if the first argument did not have a "group" attribute.

not calling self.search(); instead, call self.code.match() directly
and interpret the list of registers it returns directly.  This saves
the overhead of instantiating a MatchObject for each hit, basically
inlining search() as well as group().  When a MatchObject is still
needed, one is allocated and reused for the duration of the scan.

Added test for m.groups() with default.
Added a few prints announcing various tests in verbose mode.

O_getattr():  Added read-only access to the closed attribute, based on comment
