dyndbdel - delete a record from a dynamic database
dyndbget dbfile key
dyndbdel searches for a record with key key in a dynamical database. if key is not found then dyndbget exits 1.
If key is found then the record B<key> belongs to is made unavailable, and dyndbdel exits 0.
If dyndbdel encounters a read error, write error, or database format error, it prints an error message and exits 111.
Unavailable records are just that: they are not really deleted, but the stored hash of the key is changed to a value not matching the key. The disk space cannot be reclaimed.
