Binary package “ruby-dbm” in ubuntu lunar

wrapper for the UNIX-style Database Manager Library

 This package provides a consistent API for different possible DBM libraries.
 Dbm databases do not have tables or columns; they are simple key-value data
 stores, like a Ruby Hash except not resident in RAM. Keys and values must be
 strings.
 .
 The Debian build uses the GNU implementation of dbm (gdbm) as backend.
