pandoc (0.45) unstable; urgency=low [ John MacFarlane ] * Simplified parsing of reference keys and notes in markdown and RST readers: The Reference data structure from Text.Pandoc.Shared is no longer needed, since referenceKey and noteBlock parses return strings (as many blank lines as are occuried by the key or note) and update state themselves. getPosition and setPosition are now used to ensure that error messages will give the correct line number. This yields cleaner (and slightly faster) code, with more accurate parsing error messages. * HTML reader: + Fixed bug: parser for minimized attributes should not swallow trailing spaces. + Simplified HTML attribute parsing. + Changed parsing of code blocks in HTML reader: tag is no longer needed. 
 suffices. All HTML tags in the code block
      (e.g. for syntax highlighting) are skipped, because they are not
      portable to other output formats. ... not surrounded
      by 
 now counts as inline HTML, not code block.
    + Remove just one leading and one trailing newline from contents of
      
...
 in codeBlock parser.
 
  * Markdown reader: Require space before title in links and references.
    This fixes a bug in parsing URLs like http://silly/url(withparen).

  * RST reader:

    + Fixed bug in parsing of code blocks. Previously a full tab indent
      was required, but RST allows code to be indented any amount.
      Resolves Issue #27.
    + Allow field lists to be indented.
    + Parse the contents of field lists instead of treating as a raw string.
    + Represent field lists as definition lists instead of blockquotes. 
    + Fixed bug in which metadata would be overridden if the document
      contained multiple field lists.
    + Parse fields associated with '.. image::' blocks, and use 'alt'
      field, if given, for image alt and title attributes.  

  * LaTeX reader: Modified specialChar so that '"' characters are parsed.

  * HTML writer: Don't produce HTML for table of contents if there are
    no headers. (This would be an empty list, which is invalid XHTML.)

  * Markdown writer:
  
    + Don't print title attribute if title is empty. (This differs from
      the behavior of Markdown.pl, and agrees with PHP Markdown. But John
      Gruber has indicated that he prefers this behavior.) Adjusted test
      suite accordingly.
    + Fixed incorrect line wrapping in paragraphs including hard line
      breaks. Resolves Issue #25.
    + Fixed bug in markdown writer:  If an ordered list item began with
      a marker greater than 3 characters in width, and the item took more
      than one line, it would appear on the line after the list marker,
      e.g.:
  
          (12)
              My list item.
              Multiline.
      
      Now it works as follows:
      
          (12) My list item.
              Multiline.
  
  * RST writer
  
    + Fixed bug in RST writer's handling of ordered lists. Previously,
      list items with multiple lines would not always line up with
      single-line list items. Now, list items are nested the length of
      the list marker + 1. This looks better and ensures that list items
      all line up. (Note that list markers are padded to the length of
      the longest list marker in the series.)
    + Use 3-space indent for unordered lists.
    + If label for a link reference contains a colon, surround it by `
      signs so it won't be interpreted as the end of the link label.

  * LaTeX writer:  Cleaner output for footnotes.  Footnotes now always
    begin on a new line, and the final } is on a line by itself only
    when it needs to be (i.e. only when the note ends with a Verbatim
    environment).

  * Text.Pandoc.Shared:  save and restore position in parseFromString,
    so that accurate error messages can be given.

  * Text.Pandoc.UTF8:  modified fromUTF8 to strip out the BOM
    if present.  Windows Notepad and other applications insert a
    BOM at the beginning of a UTF8 file.

  * Main.hs (tabFilter): Treat '\r' at end of line as newline (in
    addition to "\r\n" and '\n').

  * Added a writer option for wrapped text and a command-line option
    '--no-wrap', which disables text wrapping and minimizes whitespace
    in HTML. (Resolves Issue #26.)

    + Added support for '--no-wrap' to Main.hs.
    + Added wrapIfNeeded function to Text.Pandoc.Shared.
    + Use wrapIfNeeded instead of wrapped in the RST, Man, Docbook, and
      Markdown writers.
    + Added render and renderFragment helpers to HTML writer.
    + Note: Not yet implemented in LaTeX or ConTeXt writers.

  * Modified html2markdown to run tidy only if the HTML cannot be
    parsed. Previously html2markdown piped all input through tidy
    before passing it to pandoc. This caused problems on certain pages
    (e.g. http://daringfireball.com/markdown) which have well-formed
    XHTML that causes tidy to choke. The solution is to pipe through
    tidy only if pandoc cannot parse the input by itself. This means
    that a temp file is now always used, even when input comes from a
    local file or standard input.

  * Removed 'version' constant from Main.hs; added 'pandocVersion' to
    Text.Pandoc library.

  * Fixed MacPorts Portfile:

    + Modified to install the pandoc library in addition to programs.  
    + Installation must be done manually rather than using Makefile's
      install-all.
    + Note that the library must be registered in the activate phase,
      after the library files have been copied out of the destroot.
      Cabal generates a 'register.sh' script that will do this.

  * debian/control: Added libghc6-network-dev, libghc6-xhtml-dev, and
    libghc6-mtl-dev as dependencies for libghc6-pandoc-dev.
    Closes: #445235

  * Changed pandoc home page to http://johnmacfarlane.net/pandoc/.

  [ Recai Oktaş ]

  * Makefile: fix the issue of having two copies of the library documentation
    under some usage scenarios.

pandoc (0.44) unstable; urgency=low

  [ John MacFarlane ]

  * Fixed bug in HTML writer:  when --toc was used, anchors were put around
    headers, which is invalid XHTML (block content within inline element).
    Now the anchors are put inside the header tags.  Resolves Issue #23.

  * Added xmlns attribute to html element in html writer tests.
    This attribute is added by more recent versions of the
    xhtml library (>= 3000), and is required for valid XHTML.

  [ Recai Oktaş ]

  * On configure, compile 'Setup.hs' to 'setup' and use 'setup' as the build
    command instead of 'runhaskell', which, on some platforms (such as s390,
    alpha, m68k), throws the following error:

        runhaskell Setup.hs configure --prefix=/usr
        ghc-6.6.1: not built for interactive use

    This causes a serious FTBFS bug.  Closes: #440668.

pandoc (0.43) unstable; urgency=low

  [ John MacFarlane ]

  * The focus of this release is performance.  The markdown parser
    is about five times faster than in 0.42, based on benchmarks
    with the TextMate manual. 

  * Main.hs: Replaced CRFilter and tabFilter with single function
    tabFilter, which operates on the whole string rather than breaking
    it into lines, and handles dos-style line-endings as well as tabs.

  * Added separate LaTeX reader and native reader tests; removed
    round-trip tests.

  * Text.Pandoc.Shared:

    + Removed tabsToSpaces and tabsInLine (they were used only in Main.hs.)
    + General code cleanup (to elimante warnings when compiling with -Wall.)
    + Added 'wrapped' function, which helps wrap text into paragraphs,
      using the prettyprinting library.
    + Rewrote charsInBalanced and charsInBalanced'.
        - Documented restriction: open and close must be distinct characters.
        - Rearranged options for greater efficiency.
        - Bug fix: Changed inner call to charsInBalanced inside
          charsInBalanced' to charsInBalanced'.
    + anyLine now requires that the line end with a newline (not eof).
      This is a harmless assumption, since we always add newlines to the
      end of a block before parsing with anyLine, and it yields a 10% speed
      boost.
    + Removed unnecessary 'try' in anyLine.
    + Removed unneeded 'try' from romanNumeral parser.
    + Use notFollowedBy instead of notFollowedBy' in charsInBalanced.
    + Removed unneeded 'try' in parseFromString.
    + Removed unneeded 'try' from stringAnyCase.  (Now it behaves
      like 'string'.)
    + Changed definition of 'enclosed' in Text.Pandoc.Shared so that
      'try' is not automatically applied to the 'end' parser. Added
      'try' in calls to 'enclosed' where needed. Slight speed increase.

  * Writers:

    + Replaced individual wrapping routines in RST, Man, and Markdown
      writers with 'wrapped' from Text.Pandoc.Shared.
    + Rewrote LaTeX writer to use the prettyprinting library,
      so we get word wrapping, etc.
    + Modified latex writer tests for new latex writer using prettyprinter.
    + Fixed bug in LaTeX writer: autolinks would not cause
      '\usepackage{url}' to be put in the document header. Also, changes
      to state in enumerated list items would be overwritten.
    + In Markdown writer, escape paragraphs that begin with ordered list
      markers, so they don't get interpreted as ordered lists.

  * Text.Pandoc.Reades.LaTeX:

    + Fixed bug in LaTeX reader, which wrongly assumed that the roman
      numeral after "enum" in "setcounter" would consist entirely of
      "i"s. 'enumiv' is legitimate.
    + LaTeX command and environment names can't contain numbers.
    + Rearranged order of parsers in inline for slight speed improvement.
    + Added '`' to special characters and 'unescapedChar'.

  * Text.Pandoc.Readers.RST:

    + Removed unneeded try's in RST reader; also minor code cleanup.
    + Removed tabchar.
    + Rearranged parsers in inline (doubled speed).

  * Text.Pandoc.Readers.Markdown:

    + Skip notes parsing if running in strict mode. (This yields a nice
      speed improvement in strict mode.)
    + Simplify autolink parsing code, using Network.URI to test for
      URIs. Added dependency on network library to debian/control and
      pandoc.cabal.
    + More perspicuous definition of nonindentSpaces.
    + Removed unneeded 'try' in 'rawLine'.
    + Combined linebreak and whitespace into a new whitespace parser, to
      avoid unnecessary reparsing of space characters.
    + Removed unnecessary 'try' in 'codeBlock', 'ellipses', 'noteMarker',
      'multilineRow', 'dashedLine', 'rawHtmlBlocks'.
    + Use lookAhead in parsers for setext headers and definition lists
      to see if the next line begins appropriately; if not, don't waste
      any more time parsing.
    + Don't require blank lines after code block. (It's sufficient to
      end code block with a nonindented line.)
    + Changed definition of 'emph': italics with '_' must not
      be followed by an alphanumeric character. This is to help
      prevent interpretation of e.g. [LC_TYPE]: my_type as
      '[LCTYPE]:mytype'.
    + Improved Markdown.pl-compatibility in referenceLink: the two parts
      of a reference-style link may be separated by one space, but not
      more... [a] [link], [not]    [a link].
    + Fixed markdown inline code parsing so it better accords with
      Markdown.pl: the marker for the end of the code section is a clump
      of the same number of `'s with which the section began, followed
      by a non-` character. So, for example,
         ` h ``` i ` -> h ``` i.
    + Split 'title' into 'linkTitle' and 'referenceTitle', since the
      rules are slightly different.
    + Rewrote 'para' for greater efficiency.
    + Rewrote link parsers for greater efficiency.
    + Removed redundant 'referenceLink' in definition of inline (it's
      already in 'link').
    + Refactored escapeChar so it doesn't need 'try'.
    + Refactored hrule for performance in Markdown reader.
    + More intelligent rearranging of 'inline' so that most frequently
      used parsers are tried first.
    + Removed tabchar parser, as whitespace handles tabs anyway.

  * Text.Pandoc.CharacterReferences:

    + Refactored.
    + Removed unnecessary 'try's for a speed improvement.
    + Removed unnecessary '&' and ';' from the entity table.

  * Build process:

    + Makefile: Get VERSION from cabal file, not Main.hs.
    + Modified MacPorts Portfile:
        - Depend on haddock
        - Build and install libraries and library documentation in
          addition to pandoc executable
        - Added template item for md5 sum in Portfile.in.
        - Incorporated changes from MacPorts repository (r28278).
    + FreeBSD port:  Don't try to generate distinfo in Makefile.
      It can be made using 'make makesum' in FreeBSD.
    + Make both freebsd and macports targets depend on tarball.

  * Website and documentation:

    + Updated INSTALL instructions.
    + Added pandocwiki demo to website.
    + Removed local references to Portfile, since pandoc is now in the
      MacPorts repository.

pandoc (0.42) unstable; urgency=low

  [ John MacFarlane ]

  * Main.hs: Use utf8 conversion on the extra files loaded with
    the -H, -C, -B, and -A options.  This fixes problems with unicode
    characters in these files.

  * Exposed Text.Pandoc.ASCIIMathML, since it is imported in
    Text.Pandoc.Readers.HTML and without it we get a linking error when
    using the library.

  * Markdown reader:

    + Added new rule for enhanced markdown ordered lists: if the list
      marker is a capital letter followed by a period (including a
      single-letter capital roman numeral), then it must be followed by
      at least two spaces. The point of this is to avoid accidentally
      treating people's initials as list markers: a paragraph might begin,
      "B. Russell was an English philosopher," and this shouldn't be
      treated as a list.  Documented change in README.
    + Blocks that start with "p. " and a digit are no longer treated
      as ordered lists (it's a page number).
    + Added a needed 'try' to listItem.
    + Removed check for a following setext header in endline.
      A full test is too inefficient (doubles benchmark time), and the
      substitute we had before is not 100% accurate.
    + Don't use Code elements for autolinks if --strict specified. 

  * LaTeX writer:  When a footnote ends with a Verbatim environment, the
    close } of the footnote cannot occur on the same line or an error occurs.
    Fixed this by adding a newline before the closing } of every footnote.

  * HTML writer:
    + Removed incorrect "{}" around style information in HTML tables.
      Column widths now work properly in HTML.
    + If --strict option is specified (and --toc is not), don't include
      identifiers in headers, for better Markdown compatibility.

  * Build process:

    + Separated $(web_dest) and website targets.
    + In website, index.txt is now constructed from template index.txt.in.
    + Added freebsd target to Markefile. This creates the freebsd Makefile
      from Makefile.in, and creates distinfo.  Removed Makefile and distinfo
      from the repository.
    + Added macport target to Makefile. Portfile is built from template
      Portfile.in.
    + Removed OSX package targets.  (Too many difficulties involving
      dependencies on dynamic libraries.)
    + More complete INSTALL instructions for all architectures.

  * Website:
    + Added a programming demo, pandocwiki.

  [ Recai Oktaş ]

  * Do not forget to close pandoc's ITP.  Closes: #391666

pandoc (0.41) unstable; urgency=low

  [ John MacFarlane ]

  * Fixed bugs in HTML reader:
    + Skip material at end *only if*  is present (previously,
      only part of the document would be parsed if an error was
      found; now a proper error message is given).
    + Added new constant eitherBlockOrInline with elements that may
      count either as block-level or as inline. Modified isInline and
      isBlock to take this into account.
    + Modified rawHtmlBlock to accept any tag (even an inline tag):
      this is innocuous, because rawHtmlBlock is tried only if a regular
      inline element can't be parsed.
    + Added a necessary 'try' in definition of 'para'.

  * Fixed bug in markdown ordered list parsing.  The problem was that
    anyOrderedListStart did not check for a space following the
    ordered list marker.  So in 'A.B. 2007' the parser would be
    expecting a list item, but would not find one, causing an error.
    Fixed a similar bug in the RST reader.  Resolves Issue #22.

  * Refactored RST and Markdown readers using parseFromString.

  * LaTeX reader will now skip anything after \end{document}.

  * Fixed blockquote output in markdown writer: previously, block
    quotes in indented contexts would be indented only in the first
    line.

  * Added note to INSTALL about variations in versions of the xhtml
    library that can lead to failed tests (thanks to Leif LeBaron).

 -- Recai Oktaş   Sun, 19 Aug 2007 23:26:07 +0300

pandoc (0.4) unstable; urgency=low

  [ John MacFarlane ]

  * Added two new output formats: groff man pages and ConTeXt. By
    default, output files with extensions ".ctx" and ".context" are
    assumed to be ConTeXt, and output files with single-digit extensions
    are assumed to be man pages.

  * Enhanced ordered lists (documented in README, under Lists):
    + The OrderedList block element now stores information about
      list number style, list number delimiter, and starting number.
    + The readers parse this information when possible.
    + The writers use this information to style ordered lists.
    + The enhancement can be disabled using the --strict option. 

  * Added support for tables (with a new Table block element). Two kinds
    of tables are supported: a simple table with one-line rows, and a
    more complex variety with multiline rows. All output formats are
    supported, but only markdown tables are parsed at the moment. The
    syntax is documented in README.

  * Added support for definition lists (with a new DefinitionList block
    element). All output and input formats are supported. The syntax is
    documented in README.

  * Added support for superscripts and subscripts (with new Superscript
    and Subscript inline elements).  All input and output
    formats.  The syntax is documented in README.

  * Added support for strikeout (with a new Strikeout inline element).
    All input and output formats are supported. Thanks to Bradley Kuhn,
    who contributed a patch. The syntax is documented in README. Resolves
    Issue #18.

  * Added a --toc|--table-of-contents option.  This causes an automatically
    generated table of contents (or an instruction that creates one) to
    be inserted at the beginning of the document. Not supported in S5,
    DocBook, or man page writers.

  * Modified the -m|--asciimathml option:

    + If an optional URL argument is provided, a link is inserted
      instead of the contents of the ASCIIMathML.js script.
    + Nothing is inserted unless the document actually contains
      LaTeX math.

  * Removed Blank block element as unnecessary.

  * Removed Key and Note blocks from the Pandoc data structure. All
    links are now stored as explicit links, and note contents are
    stored with the (inline) notes.

    + All link Targets are now explicit (URL, title) pairs; there
      is no longer a 'Ref' target.
    + Markdown and RST parsers now need to extract data from key and
      note blocks and insert them into the relevant inline elements.
      Other parsers have been simplified, since there is no longer any need
      to construct separate key and note blocks.
    + Markdown, RST, and HTML writers need to construct lists of
      notes; Markdown and RST writers need to construct lists of link
      references (when the --reference-links option is specified); and
      the RST writer needs to construct a list of image substitution
      references. All writers have been rewritten to use the State monad
      when state is required.
    + Several functions (generateReference, keyTable,
      replaceReferenceLinks, replaceRefLinksBlockList, and some auxiliaries
      used by them) have been removed from Text.Pandoc.Shared, since
      they are no longer needed. New functions and data structures
      (Reference, isNoteBlock, isKeyBlock, isLineClump) have been
      added. The functions inTags, selfClosingTag, inTagsSimple, and
      inTagsIndented have been moved to the DocBook writer, since that
      is now the only module that uses them. NoteTable is now exported
      in Text.Pandoc.Shared.
    + Added stateKeys and stateNotes to ParserState; removed stateKeyBlocks,
      stateKeysUsed, stateNoteBlocks, stateNoteIdentifiers, stateInlineLinks. 
    + Added writerNotes and writerReferenceLinks to WriterOptions.

  * Added Text.Pandoc module that exports basic readers, writers,
    definitions, and utility functions. This should export everything
    needed for most uses of Pandoc libraries. The haddock documentation
    includes a short example program.

  * Text.Pandoc.ASCIIMathML is no longer an exported module.

  * Added Text.Pandoc.Blocks module to help in printing markdown
    and RST tables.  This module provides functions for working with
    fixed-width blocks of text--e.g., placing them side by side, as
    in a table row.

  * Refactored to avoid reliance on Haskell's Text.Regex library, which
    (a) is slow, and (b) does not properly handle unicode.  This fixed
    some strange bugs, e.g. in parsing S-cedilla, and improved performance.

    + Replaced 'gsub' with a general list function  'substitute'
      that does not rely on Text.Regex.
    + Rewrote extractTagType in HTML reader so that it doesn't use
      regexs.
    + In Markdown reader, replaced email regex test with a custom email
      autolink parser (autoLinkEmail). Also replaced selfClosingTag regex
      with a custom function isSelfClosingTag.
    + Modified Docbook writer so that it doesn't rely on Text.Regex for
      detecting 'mailto' links.
    + Removed escapePreservingRegex and reamped entity-handling
      functions in Text.Pandoc.Shared and Text.Pandoc.CharacterReferences to
      avoid reliance on Text.Regex (see below on character reference
      handling changes).

  * Renamed Text.Pandoc.Entities as Text.Pandoc.CharacterReferences.

  * Changed handling of XML entities.  Entities are now parsed (and unicode
    characters returned) in the Markdown and HTML readers, rather than being
    handled in the writers.  In HTML and Docbook writers, UTF-8 is now used
    instead of entities for characters above 128.  This makes the HTML and 
    DocBook output much more readable and more easily editable.

    + Removed sgmlHexEntity, sgmlDecimalEntity, sgmlNamedEntity, and
      sgmlCharacterEntity regexes from Text.Pandoc.Shared.
    + Renamed escapeSGMLChar to escapeCharForXML.  Added escapeStringForXML.
      Moved both functions to Text.Pandoc.Writers.Docbook.
    + Added characterReference parser to Text.Pandoc.CharacterReferences.
      This parses a string and return a unicode character.
    + Rewrote decodeCharacterReferences to use the new parser instead of 
      Text.Regex.
    + Added new charRef parser for Markdown and HTML, which replaces the
      old 'entity' parser. Added '&' as a special character in Markdown reader.
    + Modified HTML and Markdown readers to call decodeEntities on all raw
      strings (e.g. authors, dates, link titles), to ensure that no 
      unprocessed entities are included in the native representation of
      the document.  (In the HTML reader, most of this work is done by a 
      change in extractAttributeName.)
    + In XML and Markdown output, escape unicode nonbreaking space as ' ', 
      since a unicode non-breaking space is impossible to distinguish visually
      from a regular space.  (Resolves Issue #3.)
    + Removed encodeEntitiesNumerical.
    + Use Data.Map for entityTable and (new) reverseEntityTable, for a
      slight performance boost over the old association list.
    + Removed unneeded decodeEntities from 'str' parser in HTML and
      Markdown readers.

  * Text.Pandoc.UTF8:  Renamed encodeUTF8 to toUTF8, decodeUTF8 to
    fromUTF8, for clarity.

  * Replaced old haskell98 module names replaced by hierarchical module
    names, e.g. List by Data.List.  Removed haskell98 from dependencies
    in pandoc.cabal, and added mtl (needed for state monad). Substituted
    xhtml for html.

  * Refactored and cleaned up character escaping in writers, using
    backslashEscapes and escapeStringUsing functions.

  * Instead of adding "\n\n" to the end of an input string in Main.hs,
    this is now done in the readers. This makes the libraries behave
    the way you'd expect from the pandoc program. Resolves Issue #10.

  * URLs and email addresses in autolinks are now typeset as Code.

  * In Main.hs, changed putStr to putStrLn -- mainly because MacOS X
    doesn't display the whole output unless there's a line ending.

  * Major code cleanup in all modules, for greater consistency, concision,
    and readability.

  * HTML reader:

    + Fixed several bugs (extractTagType, attribute parsing).
    + Remove Null blocks in lists of blocks when possible.
    + Allow HTML comments as raw HTML inline.

  * Markdown reader:

    + Ordered list items may no longer begin with uppercase letters, or
      letters greater than 'n'.  (This prevents first initials and page
      reference, e.g. 'p. 400', from being parsed as beginning lists.)
      Also, numbers beginning list items may no longer end with ')',
      which is now allowed only after letters.  Note: These changes
      may cause documents to be parsed differently. Users should take
      care in upgrading.
    + Changed autoLink parsing to conform better to Markdown.pl's
      behavior.  is not treated as a link, but 
      , , and 
      are.
    + Cleaned up handling of embedded quotes in link titles.  Now these are 
      stored as a '"' character, not as '"'.
    + Use lookAhead parser for the 'first pass' (looking for reference keys),
      instead of parsing normally, then using setInput to reset input.  This
      yields a slight performance boost.
    + Fixed several bugs in smart quote recognition.
    + Fixed bug in indentSpaces (which didn't properly handle
      cases with mixed spaces and tabs).
    + Consolidated 'text', 'special', and 'inline' into 'inline'.
    + Fixed bug which allowed URL and title to be separated by multiple blank
      lines in links and reference keys.  They can be on separate lines but
      can't have blank lines between them.
    + Correctly handle bracketed text inside inline footnotes and links,using
      new function inlinesInBalanced.  Resolves Issue #14. 
    + Fixed bug in footnotes: links in footnotes were not being
      processed. Solution: three-stage parse. First, get all the
      reference keys and add information to state. Next, get all the
      notes and add information to state. (Reference keys may be needed
      at this stage.) Finally, parse everything else.
    + Replaced named constants like 'emphStart' with literals.
    + Removed an extra occurance of escapedChar in definition of inline.

  * RST reader:

    + Allow the URI in a RST hyperlink target to start on the line
      after the reference key.
    + Added 'try' in front of 'string', where needed, or used a different
      parser.  This fixes a bug where ````` would not be correctly parsed as
      a verbatim `.
    + Fixed slow performance in parsing inline literals in RST reader.  The 
      problem was that ``#`` was seen by 'inline' as a potential link or image.
      Fix:  inserted 'notFollowedBy (char '`')' in link parsers.
      Resolves Issue #8.
    + Use lookAhead instead of getInput/setInput in RST reader.  Removed
      unneeded getState call, since lookAhead automatically saves and
      restores the parser state.
    + Allow hyperlink target URIs to be split over multiple lines, and
      to start on the line after the reference. Resolves Issue #7.
    + Fixed handling of autolinks.

  * LaTeX reader:

    + Replaced 'choice [(try (string ...), ...]' idiom with 'oneOfStrings',
      for clarity.
    + Added clauses for tilde and caret. Tilde is \ensuremath{\sim}, and
      caret is \^{}, not \^ as before.
    + Added parsing for \url.
    + Parse \texttt{} as code, provided there's nothing fancy inside.

  * HTML writer:

    + Modified HTML writer to use the Text.XHtml library. This results
      in cleaner, faster code, and it makes it easier to use Pandoc in
      other projects, like wikis, which use Text.XHtml. Two functions are
      now provided, writeHtml and writeHtmlString: the former outputs an
      Html structure, the latter a rendered string. The S5 writer is also
      changed, in parallel ways (writeS5, writeS5String). 
    + The Html header is now written programmatically, so it has been
      removed from the 'headers' directory. The S5 header is still
      needed, but the doctype and some of the meta declarations have
      been removed, since they are written programatically. This change
      introduces a new dependency on the xhtml package.
    + Fixed two bugs in email obfuscation involving improper escaping
      of '&' in the
