First, Introduction
Cscope is an open source, free, C + + Browse tool that comes with a text-based user interface that makes it easy to find information such as where a function or variable is defined, where it is called, and so on, through Cscope. Cscope has a better support for C/C + + and can customize it to support scripting languages such as Java and Perl, and Python. Both VIM and Gvim provide a cscope interface that allows you to jump between variables, functions, files, and so on under Unix/linux with the appropriate configuration, just as flexible and easy to use as the source insight under Windows.
