Atari target is a machine language program with a standard executable
header (FF FF <2 byte start address> <2 bytes end address>
[program bytes]). These values are calculated in the crt0.s
-file from the __CODE_LOAD__ and __BSS_LOAD__ values, so keep this in
-mind if you create a custom linker config file and start moving
-segments around (see section <ref name="Reserving a memory area inside the program" id="memhole">). You can
-override this behaviour by creating your own crt0.s file and linking
-it into your program. A run vector is added to the end of the file
-($02E0 <run vector>) and is calculated using
-__CODE_LOAD__ in crt0.s.
