At runtime several environment variables can be used to control ORC.
</p>
<p><a name="ORC_DEBUG"></a><b><code class="envar">ORC_DEBUG</code>. </b>
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
higher the value to more detail is logged.
</p>
<p><a name="ORC_CODE"></a><b><code class="envar">ORC_CODE</code>. </b>
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. The value 'backup' would instruct ORC to select the C based backup
functions. Selecting 'emulate' will run the ORC code through an interpreter.
Using 'debug' enables debuggers such as gdb to create useful backtraces from
ORC-generated code
