+/** \mainpage ROC Profiler Multi Process Binary Test
+ *
+ * \section introduction Introduction
+ *
+ * The goal of this test is to test ROC profiler as a binary against a
+ * multiprocess application.Test application launches an empty kernel
+ * on multiple threads from both parent and child process.
+ *
+ * The test then parses the csv and verifies if the nuber of context collected
+ *  are equal to number of threads launched in test application.
+ *
+ * Test also does some basic verification if counter values are non-negative
