- a modified version of jQuery SuperBox! 0.9.1 - Copyright (c) 2009 Pierre Bertet (pierrebertet.net) - Licensed under the MIT (MIT-LICENSE.txt)

Features:
- support almost all sgf properties (exception: AR - arrows, LN -line, LB - only short labels supported, FG - figure, PM - print move numbers - this feature is handled in the properties of the extension not as SGF property, CA - charset);
- support game collections;
- support children style variations;
- show move numbers (if this option is selected in the preference window);
- show coordinates (if this option is selected in the preference window).

How to use:
- when you need it - start/stop the extension from the Address Bar;
- always on - if you select Autorun checkbox from the option window).

How it works:
- at startup SGF Viewer scan the web page for links to sgf files (with .sgf extension) and show an icon in the address bar;
- if the autorun checkbox from the options page is checked then highlight the .sgf links or wait for the user to start the extension by clicking on icon's extension;
- when user click on highlighted links an overlay div appear where the content of the file will be displayed;
- when it is stopped SGF Viewer restores the page to the original state.
