-These two shell scripts are what the developers use to burn CDs,
-including the FreeBSD releases made for Walnut Creek CDROM.
-
-makecdfs.sh is used to turn an arbitrary tree of files into a single
-ISO9660 (with RockRidge extensions) filesystem image.  See the top
-of the shell script for usage instructions.
-
-burncd.sh takes the filesystem image produced by makecdfs.sh and burns
-it onto a CDR drive.  If you want to simply test your CDR without wasting
-a blank, you can also do:
-
-	burncd.sh mybigtestimage dummy
-
-And it will "write" the CD without the laser turned on, so that it's
-actually untouched.
