+        *              By default, MDB creates its environment in a directory whose
+        *              pathname is given in \b path, and creates its data and lock files
+        *              under that directory. With this option, \b path is used as-is for
+        *              the database main data file. The database lock file is the \b path
+        *              with "-lock" appended.

         *              Don't perform a synchronous flush after committing a transaction. This means
         *              transactions will exhibit the ACI (atomicity, consistency, and isolation)
