Direct quote from the 'read me'…
"Disclaimer thingy: This is an enhanced version of the
original "QUAKE" font I found on the web. The stylized
"Q" and all other logos are copyright id Software (the
greatest game makers on the face of the planet)."
So with VERY complex ownership, it may be worth considering using a different font…
