+ *
+ * The Benchmark module allows you to write easily benchmarks
+ * framework in a project for timing critical part and detect slow
+ * parts of code. In addition it automatically creates data files of
+ * these benchmark, as well as a gnuplot file which can display the
+ * comparison curves of the benchmarks.
+ *
+ * @section tutorial_benchmark_basic_usage Basic Usage
+ *
+ * To create a basic benchmark, you have to follow these steps:
+ *
+ * @li Create a new bechmark
+ * @li Write the functions that wraps the the functions you want to
+ * bechmark.
+ * @li Register these wrappers functions.
+ * @li Run the benchmark.
+ * @li Free the memory.
+ *
+ * Here is a basic example of bechmark which creates two functions
+ * that will be run. These functions just print a message.
+ *
+ * @code
+ * #include <stdlib.h>
+ * #include <stdio.h>
+ *
+ * #include <Eina.h>
+ *
+ * static
+ * void work1(int request)
+ * {
+ * printf ("work1 in progress... Request: %d\n", request);
+ * }
+ *
+ * static
+ * void work2(int request)
+ * {
+ * printf ("work2 in progress... Request: %d\n", request);
+ * }
+ *
+ * int main()
+ * {
+ * Eina_Benchmark *test;
+ * Eina_Array *ea;
+ *
+ * if (!eina_init())
+ * return EXIT_FAILURE;
+ *
+ * test = eina_benchmark_new("test", "run");
+ * if (!test)
+ * goto shutdown_eina;
+ *
+ * eina_benchmark_register(test, "work-1", EINA_BENCHMARK(work1), 200, 300, 10);
+ * eina_benchmark_register(test, "work-2", EINA_BENCHMARK(work2), 100, 150, 5);
+ *
+ * ea = eina_benchmark_run(test);
+ *
+ * eina_benchmark_free(test);
+ * eina_shutdown();
+ *
+ * return EXIT_SUCCESS;
+ *
+ * shutdown_eina:
+ * eina_shutdown();
+ *
+ * return EXIT_FAILURE;
+ * }
+ * @endcode
+ *
+ * As "test", "run" are passed to eina_benchmark_new() and as the tests
+ * "work-1" and "work-2" are registered, the data files
+ * bench_test_run.work-1.data and bench_test_run.work-2.data will be
+ * created after the eina_benchmark_run() call. They contain four
+ * columns. The file bench_test_run.work-1.data contains for example:
+ *
+ * @code
+ * # specimen experiment time starting time ending time
+ * 200 23632 2852446 2876078
+ * 210 6924 2883046 2889970
+ * 220 6467 2895962 2902429
+ * 230 6508 2908271 2914779
+ * 240 6278 2920610 2926888
+ * 250 6342 2932830 2939172
+ * 260 6252 2944954 2951206
+ * 270 6463 2956978 2963441
+ * 280 6347 2969548 2975895
+ * 290 6457 2981702 2988159
+ * @endcode
+ *
+ * The first column (specimen) is the integer passed to the work1()
+ * function when the test is run. The second column (experiment time)
+ * is the time, in nanosecond, that work1() takes. The third and
+ * fourth columnd are self-explicit.
+ *
+ * You can see that the integer passed work1() starts from 200 and
+ * finishes at 290, with a step of 10. These values are computed withe
+ * last 3 values passed to eina_benchmark_register(). See the document
+ * of that function for the detailed behavior.
+ *
+ * The gnuplot file will be named bench_test_run.gnuplot. Just run:
+ *
+ * @code
+ * gnuplot bench_test_run.gnuplot

+ *
+ * In this section, several test will be created and run. The idea is
+ * exactly the same than in the previous section, but with some basic
+ * automatic way to run all the benchmarks. The following code
+ * benchmarks some Eina converts functions, and some Eina containers
+ * types:
