|br| Conditional inclusion of some part of the ``.mod`` file. The lines

between ``@#if``, ``@#ifdef``, or ``@#ifndef`` and the next ``@#elseif``,
``@#else`` or ``@#endif`` is executed only if the condition evaluates to
``true``. Following the ``@#if`` body, you can zero or more ``@#elseif``
branches. An ``@#elseif`` condition is only evaluated if the preceding
``@#if`` or ``@#elseif`` condition evaluated to ``false``. The ``@#else``
branch is optional and is only evaluated if all ``@#if`` and ``@#elseif``
statements evaluate to false.
Note that when using ``@#ifdef``, the condition will evaluate to ``true``
if the MACRO_VARIABLE has been previously defined, regardless of its
value. Conversely, ``@#ifndef`` will evaluate to true if the MACRO_VARIABLE
has not yet been defined.
Note that when using ``@#elseif`` you can check whether or not a variable
has been defined by using the ``defined`` operator. Hence, to enter the
body of an ``@#elseif`` branch if the variable ``X`` has not been defined,
you would write: ``@#elseif !defined(X)``.
Note that if a real appears as the result of the MACRO_EXPRESSION, it
will be interpreted as a boolean; a value of ``0`` is interpreted as ``false``,
otherwise it is interpreted as ``true``. Further note that because of the
