+=== Log Warning
+
+Currently there is a intermittent benign warning message that is emitted during a run of Asciidoclet stating the following:
+
+....
+WARN: tilt autoloading 'tilt/haml' in a non thread-safe way; explicit require 'tilt/haml' suggested.
+....
+
+Unfortunately, until the underlying library removes this warning message, it will be logged during the build.
+
