+   sections.
+
+   While technically any code can be put in the init and fini sections
+   most stuff will not work other than stuff which obeys the call frame
+   and ABI.  All the call-preserved registers are saved, the call clobbered
+   registers should have been saved by the code calling init and fini.
+
+   See crtstuff.c for an example of code that inserts itself in the init
+   and fini sections. 
+
+   See crt0.s for the code that calls init and fini.  */
