+# VxWorks Munching Feature
+# When compiling C++ sources on VxWorks in kernel mode, all .o files have to
+# be processed by the so-called 'munch' script which will generate
+# additional code for static c'tors and d'tors. The resulting .c file has to
+# be compiled in turn and linked to the executable.
+# This can only been done when linking applications, since the munch script
+# generates a .c file containing static symbols: linking a lib that was
+# already munched to a munched application would lead to duplicate symbols!
