<sect1>Builtin configurations<p>
-The builtin configurations are part of the linker source. They are also
-distributed together with the machine specific binary packages (usually in the
-doc directory) and don't have a special format. So if you need a special

<sect>Special segments<p>
The builtin config files do contain segments that have a special meaning for
and the libraries. It is placed in its own segment because it needs to be
loaded at the lowest possible program address on several platforms.
-<sect1>HEAP<p>
+<sect1>ZPSAVE<p>
-This segment defines the location of the memory heap used by the malloc
-routine.
+The ZPSAVE segment contains the original values of the zeropage locations used
+by the ZEROPAGE segment. It is placed in its own segment because it must not be
+initialized.
