[Freeciv] how to go about hacking the code

["Vibhu Rishi" <vibhu.rishi@xxxxxxxxx>]

Hi,
Cheers for a great game !

Are there any existing design docs for the game ? Where do I start 
looking for the algos and the techniques that go in making the game ?
If I want to make a similar game, how do I go about it ? Is all that is 
existing as way of documentation only in the code or are some other 
documents also there ? Could you please pass on the link to the docs ?
I did try going through the code , but since I am not too good at 
programming , I am having a tough time trying to make sense of the code, 
though I would dearly like to be able to do so, probably with a little 
help from you folks.
To be very specific, this is what I am looking for :
1) AI algorithms.
2) Client window design.

Thanks,

Vibhu..
