-* Do what thou wilt shall be the whole of the Law.
-* Snitches get stitches.
-* If someone is bothering you, a good thing to do might be rewriting their contributions in a way that leaves the code incontrovertibly improved. The best revenge is getting good hacks on.
-* What the eye sees and the mind covets, let the hand boldly seize!
-* Nam Sibyllam quidem Cumis ego ipse oculis meis vidi in ampulla pendere, et cum illi pueri dicerent: *Σίβνλλα τί ϴέλεις*; respondebat illa: *άπο ϴανεΐν ϴέλω*.
-* Code talks, bullshit walks.

-* One copy shall be locked in a safe of at least TRTL30x6/European Grade 5 strength, or a strongroom at the EN 1143-1 level. No one may see this copy.
-* One copy shall be sent to that place of which we must not speak.
