+* New configuration statements
+
+sql default {
+  config-file "file";
+  config-group "grp";
+}
+
+The `config-file' statement specifies the SQL configuration file
+to use. The `config-group' statement indicates the group in that
+file to read. The defaults for both statements depend on the
+underlying database implementation. Currently only MySQL is supported,
+so the defaults are "/etc/my.cnf" for "file", and "client" for
+"group".
+
+These options can be used to store security-sensitive information
+in another file, and thus to relax permission requirements for
+wydawca.rc.
