The Rage/Readme:
既然用得這個Script,你都識得看中文,我又無謂連個Readme寫英文了。
蘋果日報網/壹傳網使用圖像來表示廣東話字。
有些廣東字可以用「o下」表示,或者直接用廣東字「吓」。出來個效果會正好多,對吧?
這個User script 就是將那些圖像轉成文字。那 Copy and Paste 時就會完整Copy所有字。

------------------------------------------------------------------------

This is a Greasemonkey user script. To install it, you need
Greasemonkey 0.3 or later: http://greasemonkey.mozdev.org/
Then restart Firefox and revisit this script.
Under Tools, there will be a new menu item to "Install User Script".
Accept the default configuration and install.
To uninstall, go to Tools/Manage User Scripts,
select "GimmeCantonese!Jimmy", and click Uninstall.
