前言
為了友善其他人搭建dm368 ipnc3.0環境，我寫了個腳本，執行腳本就可以自動搭建好環境了，絕對的傻瓜操作了，不過有一個地方讓我很郁悶，那就是在用sed替換掉某段内容的時候(143行--156行)，替換的文本有很多行且裡面某些行必須要tab開頭(makefile要求，這裡看不出，上傳的問題)，在我寫的時候發現我必須把替換的内容靠在最左邊，如果我想放到右邊寫，替換後内容就會包含左邊的那些空格。放在最左邊導緻一點也不美觀了，誰有更好的方法可以告訴我哈，先謝謝了！ (注意：我的代碼其實是有對齊的，放上來就全部都靠左了，看不出我上面說的sed的問題了，實際情況如下圖：sed替換的内容放到了最左邊， 但我想要把sed替換的内容的每行靠右些，與上面的對齊，不知道我描述清楚了沒，呵呵。 還有，如果有人想用這個腳本的話，請自己再測試下，因為我怕上傳導緻某些tab啊空格啊變了，我不怎麼寫腳本，是以有些地方可能有更好的方法實作，希望大家提出來，一起學習下，謝謝！)
注： 内部有一些對特定檔案的處理，主要是因為我的環境是fedora14，make的版本較高和我認為ipnc3.0原始檔案裡面有個别檔案有些小bug及針對于我們自己的裝置的一些小的修改。
