The `mailutils dbm` tool manages DBM files using `libmu_dbm` The invocation syntax is:

    mailutils dbm subcommand [options] file [keys]

or

    mailutils dbm [options] subcommand file [keys]

where subcommand selects the operation mode, options modify the tool behavior and file specifies the DBM file to operate upon. Some commands allow for optional keys to be specified.

The file argument can be either a DBM file name or a Database URL.
