這裡主要感謝“馬鈴薯”提供的一個日本emacser 的部落格網站地址，在哪裡看到詳細的配置，我也是按照步驟配置的，結果成功了。不過還需要改進，有點彆扭， 得知此配置的網站：http://d.hatena.ne.jp/IMAKADO jump 首先將這個檔案download下來，放在一個路徑裡面。我的就放在 ~/.emacs.d/php/下面wget http://www.emacswiki.org/cgi-bin/wiki/download/install-elisp.el將此檔案載入到設定檔中

有時我們需要在一個機器上放置多有個網站（使用不同的連接埠），如果使用的是apache，那麼只需要修改兩個檔案即可/etc/apache2/ports.conf/etc/apache2/sites-enabled/000-default第一步：一般ports.conf中的最上面兩行是 :NameVirtualHost *:80Listen 80這表明，apache預設只使用80連接埠我們可以在這兩行下面添加兩行類似的，如NameVirtualHost *:8000Lisen 8000第二步：在00

　　1． 輸入資料隨時換行　　使用者若要在輸入資料時換行，只要通過Alt+Enter按鍵組合即可輕鬆實現。此方法同樣可使已輸入內容的儲存格在游標所在處換行。　　2． 儲存格範圍內換行　　將某個長行轉成段落並在指定地區內換行。例如：A10內容很長，欲將其顯示在A列至C列之內，步驟是：選定地區A10:C12（先選A10），選擇“編輯→填充→內容重排”，A10內容就會分布在A10:C12地區中。此法特別適合用於表格內的注釋。　　3． 調整儲存格格式換行　　選定儲存格，選擇“格式→儲存格”，在彈出的對話

1、首先總結一下Trace與Debug類的特性：  A、用法基本相同，只是Debug是在Debug本版本下使用，在Release版本下不會產生代碼，而Trace在預設情況下是開啟的，也就是說在Debug版本和Release版本下都會產生代碼。  B、都是sealed類，不能被繼承，如果這兩個類不能滿足應用要求的話只能自己實現相關功能，重新編寫所有方法，不能繼承這兩個類。2、從特性上可以看出，該兩個類用法基本相同，研究並掌握Trace與Debug類，對各類軟體調試、尋找Bug會有很大協助。
