+/** \mainpage
+ * Libqrencode is a library for encoding data in a QR Code symbol, a kind of 2D
+ * symbology.
+ *
+ * \section encoding Encoding
+ *
+ * There are two methods to encode data: <b>encoding a string/data</b> or
+ * <b>encoding a structured data</b>.
+ *
+ * \subsection encoding-string Encoding a string/data
+ * You can encode a string by calling QRcode_encodeString().
+ * The given string is parsed automatically and encoded. If you want to encode
+ * data that can be represented as a C string style (NUL terminated), you can
+ * simply use this way.
+ *
+ * If the input data contains Kanji (Shift-JIS) characters and you want to
+ * encode them as Kanji in QR Code, you should give QR_MODE_KANJI as a hint.
+ * Otherwise, all of non-alphanumeric characters are encoded as 8 bit data.
+ * If you want to encode a whole string in 8 bit mode, you can use
+ * QRcode_encodeString8bit() instead.
+ *
+ * Please note that a C string can not contain NUL characters. If your data
+ * contains NUL, you must use QRcode_encodeData().
+ *
+ * \subsection encoding-input Encoding a structured data
+ * You can construct a structured input data manually. If the structure of the
+ * input data is known, you can use this way.
+ * At first, create a ::QRinput object by QRinput_new(). Then add input data
+ * to the QRinput object by QRinput_append(). Finally call QRcode_encodeInput()
+ * to encode the QRinput data.
+ * You can reuse the QRinput data again to encode it in other symbols with
+ * different parameters.
+ *
+ * \section result Result
+ * The encoded symbol is resulted as a ::QRcode object. It will contain
+ * its version number, width of the symbol and an array represents the symbol.
+ * See ::QRcode for the details. You can free the object by QRcode_free().
+ *
+ * Please note that the version of the result may be larger than specified.
+ * In such cases, the input data would be too large to be encoded in a
+ * symbol of the specified version.
+ *
+ * \section structured Structured append
+ * Libqrencode can generate "Structured-appended" symbols that enables to split
+ * a large data set into mulitple QR codes. A QR code reader concatenates
+ * multiple QR code symbols into a string.
+ * Just like QRcode_encodeString(), you can use QRcode_encodeStringStructured()
+ * to generate structured-appended symbols. This functions returns an instance
+ * of ::QRcode_List. The returned list is a singly-linked list of QRcode: you
+ * can retrieve each QR code in this way:
+ *
+ * \code
+ * QRcode_List *qrcodes;
+ * QRcode_List *entry;
+ * QRcode *qrcode;
+ *
+ * qrcodes = QRcode_encodeStringStructured(...);
+ * entry = qrcodes;
+ * while(entry != NULL) {
+ *     qrcode = entry->code;
+ *     // do something
+ *     entry = entry->next;
+ * }
+ * QRcode_List_free(entry);
+ * \endcode
+ *
+ * Instead of using auto-parsing functions, you can construct your own
+ * structured input. At first, instantiate an object of ::QRinput_Struct
+ * by calling QRinput_Struct_new(). This object can hold multiple ::QRinput,
+ * and one QR code is generated for a ::QRinput.
+ * QRinput_Struct_appendInput() appends a ::QRinput to a ::QRinput_Struct
+ * object. In order to generate structured-appended symbols, it is required to
+ * embed headers to each symbol. You can use
+ * QRinput_Struct_insertStructuredAppendHeaders() to insert appropriate
+ * headers to each symbol. You should call this function just once before
+ * encoding symbols.
