* \brief
*
* GTGBasic is a basic interface to generate trace in various formats.
*
* \authors
* Developers are : \n
* Francois Rue - francois.rue@labri.fr \n
* Francois Trahay - francois.trahay@labri.fr \n
* Johnny Jazeix - jazeix@enseirb-matmeca.fr \n
* Kevin Coulomb - kevin.coulomb@gmail.com \n
* Mathieu Faverge - faverge@labri.fr \n
* Olivier Lagrasse - lagrasse@enseirb-matmeca.fr \n
*
* It has been initiated in 2010 by *eztrace* and *ViTE* projects
* that both needs a good library to generate traces.
