+"""Tests the includeconf argument
+
+Verify that:
+
+1. adding includeconf to the configuration file causes the includeconf
+   file to be loaded in the correct order.
+2. includeconf cannot be used as a command line argument.
+3. includeconf cannot be used recursively (ie includeconf can only
+   be used from the base config file).
+4. multiple includeconf arguments can be specified in the main config
+   file.
