Teach cpio to set uid/gid and timestamp. (Timestamp has year 2100 problem.) Note that directory timestamps are still sometimes wrong because creating things in a directory can update the timestamp. Also, cp -r has logic to ensure we can write to a directory that doesn't have write permission, cpio does not. This is fixable, but not what existing cpio does.

#!/bin/bash

# Quick and dirty check to see if anybody's leaked global variables.
# We should have this, toy_list, toybuf, and toys.
