Log Message:
Update to 0.6:

* General:

  - Docutils is now compatible with Python versions from 2.3 up to 2.6
    and convertible to 3.1 code.

    + Node.__nonzero__ returns True instead of 1.
    + use os.walk instead os.path.walk.
    + minimize "types" module where possible.
    + Backwards-compatible changes to remove python2.6 -3 deprecation warnings
    + Text nodes now subclass unicode rather than UserString
      (which is gone in python 3.0).
    + 3.0 compatibility module docutils._compat

    + Drop 2.2 compatibility workarounds.
    + Drop extras/optparse.py and extras/textwrap.py
      (stdlib modules since 2.3).

  - OpenOffice export: ODT writer moved from sandbox to Doctutils core.
  - Unix man page export: manpage writer moved from sandbox to Doctutils
    core.

  - Apply [ 1719345 ] Galician translation
  - Apply [ 1905741 ] Polish translation
  - Apply [ 1878977 ] make_id(): deaccent characters.
  - Apply [ 2029251 ] return nonzero when tests fail.
  - Fix [ 1692788 ] allow UTF-8 in style sheets.
  - Fix [ 2781629 ] support non-ASCII chars in file names.
  - Apply [ 2845002 ] let ``--no-raw`` disable raw *roles* too.
  - Fix [ 2831643 ] by renaming DirectiveError.message to DirectiveError.msg
  - Fix [ 2821266 ] --strict option works now like --halt=info.
  - Fix [ 2788716 ] DirectiveError now correctly reports source and line.
  - Fix [ 1627229 ] hyperlink references in substitutions.

  - The "newlatex" writer is orphaned.

* reStructuredText:

  - Documented Unicode characters allowed as inline markup openers,
    closers, and delimiters.
  - Allow units for all length specifications.
  - Allow percent sign in "scale" argument of "figure" and \ 
"image" directives.
  - Bugfix: The "figalign" argument of a figure now works as intended
    (aligning the figure, not its contents).
  - Align images with class "align-[right|center|left]"
    (allows setting the alignment of an image in a figure).

* docutils/nodes.py:

  - Added ``Element.__contains__`` method, for the in-operator.

* docutils/parsers/rst/states.py:

  - Apply [ 1994493 ] Patch to support all kinds of quotes in inline markup.
  - Added support for Unicode inline markup delimiters "‐ ‑ \ 
‒ – —" and
    " " (non-breaking space), and "¡ ¿" openers.

* docutils/parsers/directives/misc.py:

  - Added ``start-line`` and ``end-line`` options to "include"
    directive to select a range of lines.
  - Hard tabs in literal inclusions are replaced by spaces. This is
    configurable via the new ``tab-width`` option of the "include" \ 
directive
    (a negative tab-width prevents tab expansion).

* docutils/utils.py:

  - Add ``get_stylesheet_list`` function.
  - Apply [ 2834836 ] print info at halt

* docutils/transforms/universal.py:

  - Raise default priority of StripClasses to exclude stripped classes from
    the ToC.

* docutils/writers/html4css1/__init__.py:

  - ``--stylesheet`` and ``--stylesheet-path`` options support a comma
    separated list of stylesheets.
  - Address [ 1938891 ] Inline literal text creates "pre" span only when
    needed to prevent inter-word line wraps.
  - Use `translate` method instead of repeated `replace` calls.
  - Fix [ 1757105 ] New ``table-style`` option. Added to standard table
    classes to allow CSS styling that does not interfere with other
    table-using constructs (field lists, citations, ...).

* docutils/writers/newlatex2e/__init__.py:

  - Apply [ 1612821 ] Double quotes in literal text in Italian/German

* docutils/writers/latex2e/__init__.py (see also
  `<docs/user/docutils-05-compat.sty.html>`__) :

  - Add ``--embed-stylesheet`` option.
  - Apply [ 1474017 ] image vertical alignment is reversed.
  - Apply [ 2051599 ] multi-page tables in latex writer (from pabigot).
  - Change: has_key for dictionaries (not Nodes) to in-operator.
  - Merge adjacent citations into one latex cite command.
  - Failsave implementation of custom roles. LaTeX compilation now ignores
    unknown classes instead of aborting with an error.
  - Support custom roles based on standard roles.
  - LaTeX packages can be used as ``--stylesheet`` arguments without
    restriction. (A style sheet is now referenced with the ``\usepackage``
    command, if it ends with ``.sty`` or has no extension.)
  - Add ``bp`` to lenghts without unit (prevents LaTex errors).
  - Correctly write length unit ``pt`` as ``bp`` in LaTeX.
  - Do not convert ``px`` to ``pt`` (``px`` is supported by pdfTeX since
    2005-02-04 as a configurable length unit).
  - Do not use fontenc, nor the obsolete 'ae' and 'aeguill' packages
    if font-encoding is set to ''. LaTeX defaults to OT1 then.
  - Set sub- and superscript role argument in text mode not as math.
    Use a custom role based on sub-/superscript if you want italic shape.
  - Shorter preamble and less dependencies: Load packages and define macros
    only if required in the document.
  - Use the name prefix ``DU`` for all Docutils specific LaTeX macros.
  - New custom environments and commands with optional "classes" argument.
  - Simpler LaTeX encoding, e.g. "\%" instead of "{\%}".
  - Better conformance to Docutils specifications with ``--use-latex-toc``.
    Support for LaTeX generated ToC also with unnumbered sections.
  - If 'sectnum_xform' is False, the 'sectnum' directive triggers
    section numbering by LaTeX.
  - Use default font in admonitions and sidebar.
  - Align of image in a figure defaults to 'center'.
  - Bugfix: Newlines around targets and references prevent run-together
    paragraphs.
  - Fix internal hyperlinks.
  - Use class defaults for page margins ('typearea' now optional).
  - Float placement made configurable, default changed to "here \ 
definitely".
  - Typeset generic topic as "quote block with title".
  - Use template (file and configuration option).
  - In the default template, load cmap.sty (fix text extraction in PDF) and
    fixltx2e.sty (LaTeX patches, \textsubscript).
  - Render doctest blocks as literal blocks (fixes [ 1586058 ]).
  - Use `translate` instead of repeated `replace` calls for text encoding.
  - Hyperlinked footnotes and support for symbol footnotes and
    ``--footnote-references=brackets`` with ``--use-latex-footnotes``.
  - Complete pairs of binary options
    (``--figure-footnotes, --figure-citations, --link-stylesheet``,
    ``--use-docutils-toc, --use-docutils-docinfo, --topic-abstract``)
  - New defaults:
    - font-encoding: "T1" (formerly implicitely set by 'ae').
    - use-latex-toc: true (ToC with page numbers).
    - use-latex-footnotes: true (no mixup with figures).

* docutils/writers/manpage.py

  - Do not print version at document end, this is done by the viewer.
  - Do not print date at document end, this is done by the viewer.
  - Fix storage of docinfo fields for none standard fields.
