Description

One is supposed to use gsudo (or sudo) with care, so we are convinced that it is good to give users a lecture when they use gsudo. By "giving a lecture", I mean printing the following text.

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Proposed technical details

Printing the text above will work.

It will be better if users can determine whether the lecture is always shown or is shown just once.
