+ * \brief Options for so called "simple" filters
+ *
+ * The simple filters never change the size of the data. Specifying options
+ * for them is optional: if pointer to options is NULL, default values are
+ * used. You probably never need to specify these options, so just set the
+ * options pointer to NULL and be happy.
+ *
+ * If options with non-default values have been specified when encoding,
+ * the same options must also be specified when decoding.

+ * This setting is useful only when the same filter is used
+ * _separately_ for multiple sections of the same executable file,
+ * and the sections contain cross-section branch/call/jump
+ * instructions. In that case it is benefical to set the start
+ * offset of the non-first sections so that the relative addresses
+ * of the cross-section branch/call/jump instructions will use the
+ * same absolute addresses as in the first section.
+ *
+ * When the pointer to options is NULL, the default value is used.
+ * The default value is zero.
