+    This environment variable can be set to a number indicating the level for
+    debug logging. A value of 0 (default) results in no debug logging. The

+  <para>
+    This variable can be set to a comma separated list of flags to control the
+    code selection and execution. Supported values are: backup, emulate and
+    debug. 'Backup' would instruct ORC to select the C based backup functions.
+    'Emulate' will run the ORC code through an interpreter.
