SafeSettingsContextProcessor

+The following code will provide template access to your project settings. For security, it won't pass any setting with SECRET or PASSWORD in it.

+Save as `context_processors.py` inside your project root (or anything you like, really)
+{{{
+#!python
+# To use, add the following line to settings.py:
+# TEMPLATE_CONTEXT_PROCESSORS = ('my_project.context_processors.settings',)
+#
+# Remember, you need to use RequestContext instead of Context in your views:
+# from django.template import RequestContext
+# return render_to_response('my_app/my_template.html', {'some_var': 'foo'}, 
+#                           context_instance=RequestContext(request))
