+=head1 CONFIGURATION
+
+  To get a list of symlinks that can be created, run:   
+
+    ./oracle_sysstat_ suggest
+
+  Make symlinks:
+
+    munin-node-configure --families=contrib --suggest --shell
+    ...
+
+  The following shows example settings for this plugin:
+
+    [oracle_sysstat_*]
+      user  oracle
+      env.oracle_auth  / as SYSDBA
+      env.ORACLE_HOME  /path/to/oracle/product/version
