+ * Implementation of local continuations based on the "Labels as
+ * values" feature of gcc
+ * \author
+ * Adam Dunkels <adam@sics.se>
+ *
+ * This implementation of local continuations is based on a special
+ * feature of the GCC C compiler called "labels as values". This
+ * feature allows assigning pointers with the address of the code
+ * corresponding to a particular C label.
+ *
+ * For more information, see the GCC documentation:
+ * http://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html
+ *
+ * Thanks to dividuum for finding the nice local scope label
+ * implementation.
