simple code analysis tools?

Hey all,

Am looking for a very simplistic code analysis tool that would allow me to follow along the function calling stack without the need for a debugger, and without the need to browse through a bunch of code files. What I need is very simple and could be done with a script, but I just don't have time to do it myself. I'm thinking something that would have output like the following:

main()

somefunc1()
somefunc2()
somenestedfunc()
somefunc3()

you get the idea...it should be able to just give the basics of what functions are called where and ignore all the other code...preferably also to be able to ignore certain functions like printf() that don't help in getting familiar with the logic flow. Oh yeah, it would also be nice to have a file associated with each function so you can look it up...you know what I mean? Does anybody know of something simple like this? I don't have expensive tools, so I'm hoping there is something open source a script someone knows about...thanks!
