[Why does crt0.c have "exit(main(argc,argv,argp));"?  Isn't main called first?]

I think that crt0.c is responsible for implementing the convention that main()
is called first.  crt0.c shags some environment pointers off of the stack
and in some implementations may do other stuff.  crt0.c is called directly
by the kernel.  This also means that it is the *last* thing executed before
a user program terminates.

(Sorry if I got this wrong, but I think that's how it goes).
