Subject: BootX is now in Darwin

Hello,
	After much cleaning and polishing, BootX has been moved to 
the Darwin CVS Repository.  It should be available withing the hour. 
Basically put, BootX is the booter for Mac OS X and Darwin OS.  It 
understands loading kernels from HFS+, UFS, TFTP and even EXT2.  It 
can load kernels in Mach-O and ELF format.  There are no new features 
intended for BootX, and it is now in maintenance mode.  Feel free to 
suggest changes or enhancement.  There is limited support for boot 
PPC based Linux's, but there is little or now testing.  If you have 
comments or suggestions, please let me know.  Enjoy.
