+#  There exist several targets which are by default empty and which can be

+#  before and after some main targets. They are:

+#     .build-pre:              called before 'build' target
+#     .build-post:             called after 'build' target

+#  Main targets can be executed directly, and they are:
+#  
+#     build                    build a specific configuration
+#     clean                    remove built files from a configuration
+#     clobber                  remove all built files
+#     all                      build all configurations
+#     help                     print help mesage
+#  
+#  Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
+#  .help-impl are implemented in nbproject/makefile-impl.mk.
