+/*********************************************************************************************\
+ * Macro for SetOption synonyms
+ * 
+ * SetOption synonyms come first in the list of commands, right after the prefix.
+ * They don't need any matching function pointer, since they are handled internally.
+ * So don't forget to NOT put pointers in the functions pointers list.
+ * 
+ * The additionnal list of unsigned bytes contains the Option numbers of each synonyms
+ * in the same order. The first byte of the list contains the number of synonyms
+ * (not including the number itself). The is the number of names to skip to find the first command.
+ * 
+ * As it si cumbersome to calculate the first byte (number of synonyms), we provide the following
+ * macro `SO_SYNONYMS(<name>, <list of bytes>)`
+ * 
+ * For example:
+ * ```
+ *   SO_SYNONYMS(kLightSynonyms,
+ *     37, 68, 82, 91, 92, 105,
+ *     106,
+ *   );
+ * ```
+ * 
+ * is equivalent to:
+ * ```
+ *   const static uint8_t kLightSynonyms[] PROGMEM = {
+ *     7,   // number of synonyms, automatically calculated
+ *     37, 68, 82, 91, 92, 105,
+ *     106,
+ *   };
+ * ```
+ * 
+ * This comes very handy if you need to adjust the number of synonyms depending on #defines
