Question regarding patches

[Sheikji Nazirudeen]

Hi,
 I have recently downloaded ncurses 5.4 and installed on my system. I also 
downloaded a rolloverpatch ( a shell script). Since it did not have any 
instructions on how to go about in applying the patch, I installed the patch on 
the ncurses installation directory and when I ran the patch it asks me for the 
file to patch. I exactly don't know which file to patch, any help in this 
regard would be appreciated. Also instructions  in applying the weekly patch 
would also be helpful.
