that the Macbinary files in the "misc" directly are now directly executable
from within Mac OS. This solves a "chicken-and-egg" problem: you can't even

executable code is all in the resource fork on mac68k. In other words, a
user can now begin the installation by simply double-clicking on the Booter
program on the CD-ROM.
