+ * Pour compiler
+ * =============
+ *
+ * 1. Créer le fichier hello.pro :
+ *      +------------------------------------------------------------+
+ *      |TARGET = hello                                              |
+ *      |CONFIG += qt debug                                          |
+ *      |SOURCES += hello.cc                                         |
+ *      +------------------------------------------------------------+
+ *
+ * 2. Créer le fichier Makefile avec la commande :
+ *      $ qmake -makefile hello.pro
+ *    ou tout simplement :
+ *      $ qmake -makefile
+ *
+ * 3. Compiler avec la commande :
+ *      $ make hello
+ *    ou tou simplement :
+ *      $ make
