Configuration file
==================
Every module has a large amount of input parameters, and the corresponding default values are hard-coded directly in the source code of the module. In order to solve this problem, Mirage provides a system of *configuration file*.

The configuration file is generated during the first exection of Mirage. It creates the following file structure :
::
	/home/user
		|_.mirage
			|_ modules (modules user directory)
			|_ scenarios (scenarios user directory)
			|_ mirage.cfg (configuration file)
		

Once these files and directories are created, you could use a text editor in order to modify the text file `mirage.cfg`.
By default, the configuration file is empty. However, it is possible to manually force a given module to adopt new default values for their corresponding input parameters by modifying the configuration file.

::

	[ble_sniff]
	INTERFACE = microbit0

Here, **ble_sniff** has its parameter INTERFACE set to `microbit0` ,replacing the hardcoded default value (`ubertooth0`).
Of course, multiple modules' input parameters can be modified in the configuration file.
The syntax of this file is the following :
::

	[module_A]
	PARAM_A = valueA
	PARAM_B = valueB
	PARAM_C = valueC

	[module_B]
	PARAM_1 = value1
	PARAM_2 = value2
	[...]
