+Mediacheck documentation
+August, 2002
+
+
+Mediacheck is a tool we use to test the integrity of ISO images. The
+ISO9660 specification allows for a 512 byte region which is for
+application use. We use it to store a checksum of the ISO image. Of
+couse putting the checksum into this region will change the checksum
+of the final ISO image, so when we verify the checksum later we have
+to fill in this 512 region with the original contents before the
+implantation. It is set to all ASCII 32 decimal spaces.
+
+If you have a set of ISO images you can implant the checksum data with
+this command:
+
+ implantmd5iso <isoname>
+
+NOTE: You cannot re-implant an ISO once its been implanted.
+
+To check a ISO image you can use this command line:
+
+ checkisomd5 <isoname>
+
+The tools are in the anaconda-runtime package, currently in the
+/usr/lib/anaconda-runtime/ directory.
