Removing lintian warnings? (package games/dmagnetic)

[Thomas Dettbarn <dettus@dettus.net>]

Hello!

Currently, I am trying to get my package dMagnetic into 
Debian's repository. You can find it at 

https://mentors.debian.net/package/dmagnetic

Despite my best effords, there are still a handful of lintian warnings left. Naturally, I would like to get rid of them:



 – Package is not in Debian
– Package has lintian informational warnings
dmagnetic source

    I debian-watch-uses-insecure-uri
        http://www.dettus.net/dMagnetic
    I testsuite-autopkgtest-missing
    P rules-requires-root-missing
    X debian-watch-does-not-check-gpg-signature

 dmagnetic

    I description-synopsis-might-not-be-phrased-properly
        "Play classic textadventures from Magnetic Scrolls in glorious ANSI Art."
    I hardening-no-bindnow
        usr/games/dMagnetic
    I hardening-no-fortify-functions
        usr/games/dMagnetic



Whilst there is nothing I will be able to do about the "insecure iru" and "gpg signature", the "rules-requires-root-missing" is bugging me. 
What EXACTLY is it that I have to put into the debian/control and debian/rules files, so that this message disappears? The only root-permissions my package needs are during the installation process. Not whilst building, not whilst running.

PLEASE DO NOT JUST COPY&PASTE A LINK TO THE DOCUMENTATION IN HERE. PLEASE HELP ME.
