今天在酷！學園看到這樣一個問題：cscope 使用問題 ，很好奇cscope是什麼東西，後來Google之後才知道這個原來是用vim來trace source code的，它擁有的功能如下：
1.Allows searching code for:
all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file
2.Curses based (text screen)
3.An information database is generated for faster searches and later reference
4.The fuzzy parser supports C, but is flexible enough to be useful for C++ and Java, and for use as a 5.generalized ‘grep database’ (use it to browse large text documents!)
6.Has a command line mode for inclusion in scripts or as a backend to a GUI/frontend
7.Runs on all flavors of Unix, plus most monopoly-controlled operating systems.

我也注意到它的DOS/Windows的支援，
