How do i make sense of large codebase of cmus.

[Mohd M. A. <ala...@gm...>]

Hello,

I want to learn how the program cmus works and I want to contribute.

I have no experience in open source development and I'm a student learning
about computer science in college.

So i tried to learn by reading code by following ways.

I compile the program and run gdb on it so i found out that program starts
from ui_curses.c from line 2547.
inside main function it calling dozens of other functions and making
decision but my problem is how do i make sense of large codebase how do i
find which pieces of code does what.

I need help How do i read the large code and make sense of it.
what tools should i learn so that it can help me to understand codebase.

any advice and help will mean a lot to me.

In short i want to know what tools you use to understand cmus how do you
read source code and able to understand what each piece code does what.
what tools do i have learn apart from C.

I'm running Ubuntu 14.04.

Thanks
