Link #5 @dcaba any suggestion? improvement?

[dcaba]

Is already finished? I expected a flag like "-yes" to prevent questions, like the one we have in apt:

       -y, --yes, --assume-yes
           Automatic yes to prompts; assume "yes" as answer to all prompts and run non-interactively. If an undesirable situation, such as changing a held package,
           trying to install a unauthenticated package or removing an essential package occurs then apt-get will abort. Configuration Item: APT::Get::Assume-Yes.

I forgot about it, do you prefer yes or force?

[dcaba]

"yes" its good for me, but no strong opinion on that

@dcaba ready for review
