Mergemaster

[Net Warrior]

Hi there.

I found very tedious when , after a makeworld the mergemaster process to 
say (i) to install/upgrade/replace/  with the new file, specially when 
there are a lot of files  I was reading the documentation but it's not 
clear to me which option to use to automate the process, which is the 
right one, or combination?

-U -F -iF?

Thanks for your time and support
Regards
