Show or modify description and title of a domain. These values are user
fields that allow to store arbitrary textual data to allow easy
identification of domains. Title should be short, although it's not enforced.
Flags I<--live> or I<--config> select whether this command works on live
or persistent definitions of the domain. By default both are influenced, while
modifying and running definition is used while reading the note.
If both I<--live> and I<--config> are specified, the I<--config> option takes
precedence on getting the current description and both live configuration
and config are updated while setting the description.
or persistent definitions of the domain. If both I<--live> and I<--config>
are specified, the I<--config> option takes precedence on getting the current
description and both live configuration and config are updated while setting
the description. I<--current> is exclusive and implied if none of these was specified.
Flag I<--edit> specifies that an editor with the contents of current
description or title should be opened and the contents saved back afterwards.
