"\h|SYNOPSIS|
\c{\b{brep-migrate --help}\n
\b{brep-migrate --version}\n
\b{brep-migrate} [<options>] <schema>}
\h|DESCRIPTION|
In its default mode \cb{brep-migrate} creates the database schema if it
doesn't already exist. Otherwise, it migrates the existing schema and data
to the current version, if needed. The valid schema names are \cb{package}
and \cb{build}.
If the \cb{--recreate} option is specified, then \cb{brep-migrate} instead
recreates the database schema. That is, it drops all the existing tables
(and their data) and then creates them from scratch.
If the \cb{--drop} option is specified, then \cb{brep-migrate} drops all the
existing tables (and their data).
The \cb{--recreate} and \cb{--drop} options are mutually exclusive. When
specified, they will cause \cb{brep-migrate} to fail if the database schema
requires migration. In this case you can either migrate the database first
or drop the entire database using, for example, \cb{psql(1)}."
