92        /** @brief Real-time instrument script (sfz format extension).
93         *
94         * Real-time instrument scripts are user supplied small programs which can
95         * be used by instrument designers to create custom behaviors and features
96         * not available in the stock sampler engine. Features which might be very
97         * exotic or specific for the respective instrument.
98         *
99         * This is an extension of the sfz format, thus a feature which is currently
100         * only supported by LinuxSampler. Scripts will not load with other sfz
101         * players right now. The dedicated sfz opcode for this purpose is:
102         * @code
103         * script=path/to/scriptfile
104         * @endcode
105         * This opcode is recommended to appear in the sfz file's global section,
106         * however ATM the precise location of the opcode is simply ignored.
107         * Currently there may only be one @c script opcode per instrument. Further
108         * @c script opcodes will currently simply be ignored. In future using
109         * multiple @c script opcodes will be supported as well, the scripts will
110         * then be executed by the sampler in the order in which their opcodes
111         * appeared in their sfz file.
112         *
113         * You find more informations about Instrument Scripts on the LinuxSampler
114         * documentation site:
