+/**
+ * \mainpage
+ * The TinyCBOR $(VERSION) library is a small CBOR encoder and decoder library,
+ * optimized for very fast operation with very small footprint. The main encoder
+ * and decoder functions do not allocate memory.
+ *
+ * TinyCBOR is divided into the following groups of functions and structures:
+ *  - \ref CborGlobals
+ *  - \ref CborEncoding
+ *  - \ref CborParsing
+ *  - \ref CborPretty
+ *  - \ref CborToJson
+ */
+
+/**
+ * \file <cbor.h>
+ * The <cbor.h> is the main header in TinyCBOR and defines the constants used by most functions
+ * as well as the structures for encoding (CborEncoder) and decoding (CborValue).
+ *
+ * \sa <cborjson.h>
+ */
+
+/**
+ * \file <cborjson.h>
+ * The <cborjson.h> file contains the routines that are used to convert a CBOR
+ * data stream into JSON.
+ *
+ * \sa <cbor.h>

+ */
+
+/**
+ * \enum CborType
+ * The CborType enum contains the types known to TinyCBOR.
+ *
+ * \value CborIntegerType           Type is an integer value, positive, negative or zero
+ * \value CborByteStringType        Type is a string of arbitrary raw bytes
+ * \value CborTextStringType        Type is a text string encoded in UTF-8
+ * \value CborArrayType             Type is a CBOR array
+ * \value CborMapType               Type is a CBOR map (an associative container with key and value pairs)
+ * \value CborTagType               Type is a CBOR tag (a 64-bit integer describing the item that follows, see CborKnownTags)
+ * \value CborSimpleType            Type is one of CBOR Simple Types
+ * \value CborBooleanType           Type is a boolean (true or false)
+ * \value CborNullType              Type encodes a null
+ * \value CborUndefinedType         Type encodes an undefined value
+ * \value CborHalfFloatType         Type is an IEEE 754 half precision (16-bit) floating point type
+ * \value CborFloatType             Type is an IEEE 754 single precision (32-bit) floating point type
+ * \value CborDoubleType            Type is an IEEE 754 double precision (64-bit) floating point type
+ * \value CborInvalidType           Type is not valid (this value is used to indicate error conditions)
+ */
+
+/**
+ * \enum CborKnownTags
+ * The CborKnownTags enum contains known tags specified in RFC 7049, for use by the application.
+ * TinyCBOR does not usually interpret the meaning of these tags and does not add them to the
+ * output stream, unless specifically instructed to do so in functions for that effect.
+ *
+ * \value CborDateTimeStringTag     Text string contains a date-time encoded in RFC 3339 format, "YYYY-MM-DD hh:mm:ss+zzzz"
+ * \value CborUnixTime_tTag         Number is a Unix time_t quantity, the number of seconds since 1970-01-01 midnight UTC
+ * \value CborPositiveBignumTag     Item is a CBOR byte string encoding a positive integer of arbitrary precision
+ * \value CborNegativeBignumTag     Item is a CBOR byte string encoding a negative integer of arbitrary precision
+ * \value CborDecimalTag            Item is a CBOR array of two integers encoding a fixed-point decimal
+ * \value CborBigfloatTag           Item is a bigfloat
+ * \value CborExpectedBase64urlTag  Item is a CBOR byte string that is expected to be encoded as Base64Url
+ * \value CborExpectedBase64Tag     Item is a CBOR byte string that is expected to be encoded as Base64
+ * \value CborExpectedBase16Tag     Item is a CBOR byte string that is expected to be encoded as Base16 (also known as "hexdump")
+ * \value CborUriTag                Item is a CBOR text string containing an URI (RFC 3986) or IRI (RFC 3987)
+ * \value CborBase64urlTag          Item is a CBOR text string that was encoded as Base64Url
+ * \value CborBase64Tag             Item is a CBOR text string that was encoded as Base64
+ * \value CborRegularExpressionTag  Item is a CBOR text string containing a regular expression
+ * \value CborMimeMessageTag        Item is a CBOR text string containing a MIME message (RFC 2045, 2046, 2047, 2822)
+ * \value CborSignatureTag          Item contains CBOR-encoded data.
+ *                                  This tag is also used as "file magic," marking a file as containing CBOR
+ */

+/**
+ * \typedef CborTag
+ * This typedef is an unsigned 64-bit integer. Known CBOR tags can be used from the CborKnownTags enum
+ * but the user application may use other tag values than the ones specified in RFC 7049.
