Greg's Buttons is a control panel that lets you customize the user
interface of a Macintosh running System 7. To use it, drop it
into your "Control Panels" folder (or drop it on your "System Folder"
and let the Finder put it where it belongs) and restart. Greg's
Buttons requires that your Mac supports color, so it won't work on
the Plus, SE, Classic, or PowerBook 100. Every Mac with a 68020
processor or better supports color, even if it has a black and white
screen. Greg's Buttons works just fine on gray-scale monitors, and
although it will work on a black and white screen, the effect is much
Greg's Buttons is in FAT binary, which means it will work
optimally for both PPC and 68k machines.
