I have a simple question that has been bugging me all day.

If i have, say for example, two new addons that I want to install, but both of them share some files. How do i install them both?

Like when I tried installing a captcha addon AND an automatic login addon, one just overwrites the other.

I tried using my *nix diff command and then patching afterwards, but I jsut cannot seem to do it..

Anyone explain to me, in relatively simple steps, how I should go about installing addons that share files, without overwriting the others each time??

Please tell me i don't have to manually see what lines are different, and then work from there....
