<sect2><tt/atari-xex.cfg/<p>
This config file shows how to write a binary using the ATARI (xex) file format
support on LD65, this simplifies the memory areas and allows to add new memory
areas easily without writing new headers and trailers.
Note that the default C library includes the system-check chunk, so in this
linker configuration we suppress the importing of the header and trailer for
this chunk by defining the standard import symbols to a 0 value. For the
initialization address of the system-check chunk, the INITAD is set directly in
the configuration.

Similar to the <tt/atari-xex.cfg/ above, this config file shows how to write a
binary using the ATARI (xex) file format support on LD65.
In addition to the suppressing of the system-check headers and trailers, this
also suppresses the shadow-ram-preparation headers and trailers, but does this
by defining an "UNUSED" memory area that is not written to the output file.
