 The first task is to initialize the Environment Abstraction Layer (EAL).
 This is done in the main() function using the following code:

-    main(int argc, char **argv)
-
-    {
-        ret = rte_eal_init(argc, argv);

 This call finishes the initialization process that was started before main() is called (in case of a Linux environment).
 The argc and argv arguments are provided to the rte_eal_init() function.

 In this example, lcore_hello() is called on every available lcore.
 The following is the definition of the function:
 
-.. code-block:: c
-
-    static int
-    lcore_hello(__rte_unused void *arg)
-    {
-        unsigned lcore_id;

+    :start-after: Launch a function on lcore. 8<
+    :end-before: >8 End of launching function on lcore.
 
 The code that launches the function on each lcore is as follows:
 
-.. code-block:: c
-
-    /* call lcore_hello() on every worker lcore */
-
-    RTE_LCORE_FOREACH_WORKER(lcore_id) {
-       rte_eal_remote_launch(lcore_hello, NULL, lcore_id);

 The following code is equivalent and simpler:
