The number of byte-years in a file is the number of bytes in
the file times the number of years since it has last changed.
The "byteyears" command gives you this information for files
and looks recursively at the contents of directories.
It is useful for gaining hints as to what files might well be deleted.

Seal and ship are parts of the software distribution stuff
described in my article "Automatic Software Distribution"
in the USENIX conference proceedings, June 1984 [Salt Lake City].
