"""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.
