mkisofs is a pre-mastering program to generate an ISO 9660 file
system.  It takes a snapshot of a directory tree, and makes a binary
image which corresponds to an ISO 9660 file system when written to a
block device. It supports the Rock Ridge Interchange Protocol for
preserving Unix file system information under the ISO9660 format.

mkisofs is available via anonymous FTP from tsx-11.mit.edu
