-/* This is the canonical entry point, usually the first thing in the text
-   segment.  The SVR4/i386 ABI (pages 3-31, 3-32) says that when the entry
-   point runs, most registers' values are unspecified, except for:
-
-   %edx		Contains a function pointer to be registered with `atexit'.
-		This is how the dynamic linker arranges to have DT_FINI
-		functions called for shared libraries that have been loaded
-		before this code runs.
-
-   %esp		The stack contains the arguments and environment:
-		0(%esp)			argc
-		4(%esp)			argv[0]
-		...
-		(4*argc)(%esp)		NULL
-		(4*(argc+1))(%esp)	envp[0]
