WMD: The Wysiwym Markdown Editor
================================
Introduction
------------
WMD is a JavaScript based code editor for the [Markdown](http://daringfireball.net/projects/markdown/) formatting language. It includes a Markdown interpreter – Showdown – for live preview and output of the Markdown generated HTML.
This is a fork of WMD for ChiperSoft Systems & NFY Interactive designed for use in CMS engines. It was forked from the [Open Library fork](http://github.com/openlibrary/wmd) of WMD, which was in turn forked from the [Stackoverflow fork](http://github.com/derobins/wmd).
Major Changes from Open Library Revision
-------------
* Extended showdown to support a series of Markdown extensions:
- Link urls that start with ! are opened in a new window
- Text wrapped with double carets is made superscript (ex: `^^this text is superscripted^^`)
- Text wrapped with double commas is made subscript (ex: `,,this text is subscripted,,`)
- Text wrapped with double tildes is made strikethrough (ex: `~~this text is struck~~`)
- (c), (r), (tm), -- and ... are converted into their respective html entities.
- Lines prefixed with "->" are right aligned. Lines also postfixed with "<-" are center aligned.
* Several ascii characters that may produce encoding issues (such as curled quotes) are converted into entities
* Removed top level frame pollution, forcing WMD to run only in its own document.
* Removed the automatic conversion from Markdown to HTML when the form is submitted.
* Removed the automatic addition of http:// to image urls, preventing the entry of relative addresses.
* Numerous bug fixes to both WMD and Showdown
