= NVDA Design =

== nvda.pyw ==
The launcher of NVDA.

== eventHandler and scriptHandler ==
用來處理Input及API

== !InputHandler ==
處理NVDA的輸入request，而目前的input僅有mouse(由mouseHandler處理)、keybpard(由keyboardHandler處理)

== Output Modules == 
speech:

braille:

== !QueueHandler ==
處理常駐程式的request

== Virtual Buffer ==
處理較複雜的文件
如：browsers
因browser的information不一定在狀態列或其他較易處理的位址上，所以nvda(or 其他報讀軟體)必須自行建立文件的階層去處理這些information
