+       There are two ways to specify a database directory. You can either
+       specify a full path using the database-dir option or a root path
+       using the database-root option. In the latter case, a directory
+       structure matching that of the base-dir argument is created
+       below the given full path.
+
+       The advantage of using database-root is that the base-dir is

+       and you do not have to care for setting the database-dir explicitly.
