Documentation for LunarCrack:
LunarCrack is an INIT resource which causes your SysBeep trap to
"crack" the screen. To use it simply put it in your system folder
and boot. If you want to get rid of it, just pull it out of your
system folder and reboot.
LunarCrack also contains code to call your actual SysBeep routine,
so if you already have an INIT that replaces your beep, make sure
that your current beep patch is loaded first. (Make it's file name
come before the LunarCrack alphabetically.)
(Example. If you have one called "NewBeep", name it "ANewBeep",
and it will work.)
If you don't, the LunarBeep will be superceded by your other patch.
It won't bother anything, but it will still take up some space.
