How to Modify Reaver's Source Code?

I asked this question before but the response of most of you guys was aggressive towards me and instead of helping me out, you guys decided to lampoon me for not knowing such a basic thing.

Here I am, raising this question all over again. Does someone know how to access and edit Reaver's source code?

I have a bunch of code in my mind that I need to implement for the sake of removing 'AP RATE LIMITING' error which pops up when the targetted AP locks itself after receiving too many PIN attempts from the same MAC address.

Please comment only if you know what I'm asking for and you have a solution for it.

Hateful & ludicrous opinions are highly unasked for.

Thankyou.
