 this last column.  These outputs will go to a dedicated output file for each line only.  For 
 sending values to the global output file, use the Outputs section instead.

+This section (optional) describes the failure conditions of the system. Line failures can only be
+triggered at an existing point or rod end where a line/lines are attached. Failures can be 
+triggered by a time or attachment tension threshold, which ever comes first. Users can specify
+multiple failures for a given point, but duplicate failure configurations will be ignored.
+If two lines attached to a point are listed to fail (failure 1 for example), then after the failure
+the lines will remain attached to each other by a free point. In this multi line case, if any line
+reaches the tension threshold then the failure will be triggered. The theory behind failures can be
+found :ref:`here <version2>`.
