The <info>$fullName</info> command generates the SQL needed to
synchronize the database schema with the current mapping metadata of the
default entity manager.

For example, if you add metadata for a new column to an entity, this command
would generate and output the SQL needed to add the new column to the database:

<info>$fullName --dump-sql</info>

Alternatively, you can execute the generated queries:

<info>$fullName --force</info>

Finally, be aware that if the <info>--complete</info> option is passed, this
task will drop all database assets (e.g. tables, etc) that are *not* described
by the current metadata. In other words, without this option, this task leaves
untouched any "extra" tables that exist in the database, but which aren't
described by any metadata.
