This special "Extra" version of PHP Markdown features -further enhancements to the syntax for making additional constructs -such as tables and definition list. - -Markdown is a text-to-HTML filter; it translates an easy-to-read / -easy-to-write structured text format into HTML. Markdown's text format -is most similar to that of plain text email, and supports features such -as headers, *emphasis*, code blocks, blockquotes, and links. - -Markdown's syntax is designed not as a generic markup language, but -specifically to serve as a front-end to (X)HTML. You can use span-level -HTML tags anywhere in a Markdown document, and you can use block level -HTML tags (like
    and as well). - -For more information about Markdown's syntax, see: - - - - -Bugs ----- - -To file bug reports please send email to: - - - -Please include with your report: (1) the example input; (2) the output you -expected; (3) the output Markdown actually produced. - - -Version History ---------------- - -See the readme file for detailed release notes for this version. - - -Copyright and License ---------------------- - -PHP Markdown & Extra -Copyright (c) 2004-2008 Michel Fortin - -All rights reserved. - -Based on Markdown -Copyright (c) 2003-2006 John Gruber - -All rights reserved. - -Redistribution and use in source and binary forms, with or without -modification, are permitted provided that the following conditions are -met: - -* Redistributions of source code must retain the above copyright notice, - this list of conditions and the following disclaimer. - -* Redistributions in binary form must reproduce the above copyright - notice, this list of conditions and the following disclaimer in the - documentation and/or other materials provided with the distribution. - -* Neither the name "Markdown" nor the names of its contributors may - be used to endorse or promote products derived from this software - without specific prior written permission. - -This software is provided by the copyright holders and contributors "as -is" and any express or implied warranties, including, but not limited -to, the implied warranties of merchantability and fitness for a -particular purpose are disclaimed.
