+TEMPLATE_DEBUG
+--------------
+
+Default: ``False``
+
+**Only available in Django development version.**
+
+A boolean that turns on/off template debug mode. If this is ``True``, the fancy
+error page will display a detailed report for any ``TemplateSyntaxError``. This
+report contains the relevant snippet of the template, with the appropriate line
+highlighted.
+
+Note that Django only displays fancy error pages if ``DEBUG`` is ``True``, so you'll
+want to set that to take advantage of this setting.
+
+See also DEBUG.
