Chuck is trying to embed metadata in tape image files.
The only way to do this and be backwards compatible is to append
a record to the end of the image.

The argument is what the contents of that record should look like

A magic string "TAPEINFO" as the first eight bytes of that record
and colon separated keywords has been proposed for the rest.

At a minimum, the actual container format and version
the image is written in should be there!
