+#  There exist several targets which are by default empty and which can be 
+#  used for execution of your targets. These targets are usually executed 
+#  before and after some main targets. They are: 
+#
+#     .build-pre:              called before 'build' target
+#     .build-post:             called after 'build' target

+#     build                    build a specific configuration
+#     clean                    remove built files from a configuration

+#     help                     print help mesage
+#  
+#  Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
