How to make very compact code

[list][*]Use alt_main() instead of main().

[*]Copy the alt_sys_init() function that is generated in your system library over to your own source file

[*]Delete any parts of your alt_sys_init() that you don't need. Make sure to give it a different name, if you're not just copying its code straight into your alt_main().

[*]So long as you don't reference anything in alt_sys_init.c (including globals), it won't link alt_sys_init.o into your executable.

[/list]That should do it.
