When you start learning the source code of an unfamiliar project, you don't have the knowledge of its structure or the meaning of specific functions, classes, and units in the project. You can use tags to browse for definitions, but it's hard to get an overall picture by just looking through every definition one by one. Cscope and SilentBob are two tools that can help you analyze unfamiliar source code. They help you find symbol definitions, determine where specific functions are used, determine which functions are called by other given functions, and search for strings and patterns throughout the code base. With them, you can save time by doing fast, targeted searches instead of grepping through source files by hand.
