.PP
\-\-persistent
.RS 4
Open the database as a persistent database\&.
.sp
Exactly one of \-\-persistent and \-\-non\-persistent must be specified\&.
.RE
.PP
\-\-non\-persistent
.RS 4
Open the database as a non\-persistent database\&.
.sp
Caveat: opening a database as non\-persistent when there is currently no other opener will wipe the database\&.
.sp
Exactly one of \-\-persistent and \-\-non\-persistent must be specified\&.
