* Purpose: Configuration options for OSS (osscore.conf)

* Description:
* This file contains various configuration options for the osscore module.
* They can be set in the osscore.conf configuration file.
*
* Each option variable must also be defined as extern in the proper header
* file (of the subsystem that uses them) or in the source file that uses them.
