-CppBor: A Modern C++ CBOR Parser and Generator
-==============================================
-
-CppBor provides a natural and easy-to-use syntax for constructing and
-parsing CBOR messages.  It does not (yet) support all features of
-CBOR, nor (yet) support validation against CDDL schemata, though both
-are planned.  CBOR features that aren't supported include:
-
-* Indefinite length values
-* Semantic tagging
-* Floating point
-
-CppBor requires C++-17.
-
-## CBOR representation
-
-CppBor represents CBOR data items as instances of the `Item` class or,
-more precisely, as instances of subclasses of `Item`, since `Item` is a
-pure interface.  The subclasses of `Item` correspond almost one-to-one
-with CBOR major types, and are named to match the CDDL names to which
-they correspond.  They are:
-
-* `Uint` corresponds to major type 0, and can hold unsigned integers
-  up through (2^64 - 1).
-* `Nint` corresponds to major type 1.  It can only hold values from -1
-  to -(2^63 - 1), since it's internal representation is an int64_t.
-  This can be fixed, but it seems unlikely that applications will need
-  the omitted range from -(2^63) to (2^64 - 1), since it's
-  inconvenient to represent them in many programming languages.
-* `Int` is an abstract base of `Uint` and `Nint` that facilitates
-  working with all signed integers representable with int64_t.
-* `Bstr` corresponds to major type 2, a byte string.
-* `Tstr` corresponds to major type 3, a text string.
-* `Array` corresponds to major type 4, an Array.  It holds a
-  variable-length array of `Item`s.
-* `Map` corresponds to major type 5, a Map.  It holds a
-  variable-length array of pairs of `Item`s.
-* `Simple` corresponds to major type 7.  It's an abstract class since
-  items require more specific type.
-* `Bool` is the only currently-implemented subclass of `Simple`.
-
-Note that major type 6, semantic tag, is not yet implemented.
-
-In practice, users of CppBor will rarely use most of these classes
-when generating CBOR encodings.  This is because CppBor provides
-straightforward conversions from the obvious normal C++ types.
-Specifically, the following conversions are provided in appropriate
-contexts:
-
-* Signed and unsigned integers convert to `Uint` or `Nint`, as
-  appropriate.
-* `std::string`, `std::string_view`, `const char*` and
-  `std::pair<char iterator, char iterator>` convert to `Tstr`.
-* `std::vector<uint8_t>`, `std::pair<uint8_t iterator, uint8_t
-  iterator>` and `std::pair<uint8_t*, size_t>` convert to `Bstr`.
-* `bool` converts to `Bool`.
-
-## CBOR generation
-
-### Complete tree generation
-
-The set of `encode` methods in `Item` provide the interface for
-producing encoded CBOR.  The basic process for "complete tree"
-generation (as opposed to "incremental" generation, which is discussed
-below) is to construct an `Item` which models the data to be encoded,
-and then call one of the `encode` methods, whichever is convenient for
-the encoding destination.  A trivial example:
-
-```
-cppbor::Uint val(0);
-std::vector<uint8_t> encoding = val.encode();
-```
-
-    It's relatively rare that single values are encoded as above.  More often, the
-    "root" data item will be an `Array` or `Map` which contains a more complex structure.For example
-    :
-
-``` using cppbor::Map;
-using cppbor::Array;
-
-std::vector<uint8_t> vec =  // ...
-    Map val("key1", Array(Map("key_a", 99 "key_b", vec), "foo"), "key2", true);
-std::vector<uint8_t> encoding = val.encode();
-```
-
-This creates a map with two entries, with `Tstr` keys "Outer1" and
-"Outer2", respectively.  The "Outer1" entry has as its value an
-`Array` containing a `Map` and a `Tstr`.  The "Outer2" entry has a
-`Bool` value.
-
-This example demonstrates how automatic conversion of C++ types to
-CppBor `Item` subclass instances is done.  Where the caller provides a
-C++ or C string, a `Tstr` entry is added.  Where the caller provides
-an integer literal or variable, a `Uint` or `Nint` is added, depending
-on whether the value is positive or negative.
-
-As an alternative, a more fluent-style API is provided for building up
-structures.  For example:
-
-```
-using cppbor::Map;
-using cppbor::Array;
-
-std::vector<uint8_t> vec =  // ...
-    Map val();
-val.add("key1", Array().add(Map().add("key_a", 99).add("key_b", vec)).add("foo")).add("key2", true);
-std::vector<uint8_t> encoding = val.encode();
-```
-
-    An advantage of this interface over the constructor -
-    based creation approach above is that it need not be done all at once
-        .The `add` methods return a reference to the object added to to allow calls to be chained,
-    but chaining is not necessary; calls can be made
-sequentially, as the data to add is available.
-
-#### `encode` methods
-
-There are several variations of `Item::encode`, all of which
-accomplish the same task but output the encoded data in different
-ways, and with somewhat different performance characteristics.  The
-provided options are:
-
-* `bool encode(uint8\_t** pos, const uint8\_t* end)` encodes into the
-  buffer referenced by the range [`*pos`, end).  `*pos` is moved.  If
-  the encoding runs out of buffer space before finishing, the method
-  returns false.  This is the most efficient way to encode, into an
-  already-allocated buffer.
-* `void encode(EncodeCallback encodeCallback)` calls `encodeCallback`
-  for each encoded byte.  It's the responsibility of the implementor
-  of the callback to behave safely in the event that the output buffer
-  (if applicable) is exhausted.  This is less efficient than the prior
-  method because it imposes an additional function call for each byte.
-* `template </*...*/> void encode(OutputIterator i)`
-  encodes into the provided iterator.  SFINAE ensures that the
-  template doesn't match for non-iterators.  The implementation
-  actually uses the callback-based method, plus has whatever overhead
-  the iterator adds.
-* `std::vector<uint8_t> encode()` creates a new std::vector, reserves
-  sufficient capacity to hold the encoding, and inserts the encoded
-  bytes with a std::pushback_iterator and the previous method.
-* `std::string toString()` does the same as the previous method, but
-  returns a string instead of a vector.
-
-### Incremental generation
-
-Incremental generation requires deeper understanding of CBOR, because
-the library can't do as much to ensure that the output is valid.  The
-basic tool for intcremental generation is the `encodeHeader`
-function.  There are two variations, one which writes into a buffer,
-and one which uses a callback.  Both simply write out the bytes of a
-header.  To construct the same map as in the above examples,
-incrementally, one might write:
-
-```
-using namespace cppbor;  // For example brevity
-
-std::vector encoding;
-auto iter = std::back_inserter(result);
-encodeHeader(MAP, 2 /* # of map entries */, iter);
-std::string s = "key1";
-encodeHeader(TSTR, s.size(), iter);
-std::copy(s.begin(), s.end(), iter);
-encodeHeader(ARRAY, 2 /* # of array entries */, iter);
-Map().add("key_a", 99).add("key_b", vec).encode(iter)
-s = "foo";
-encodeHeader(TSTR, foo.size(), iter);
-std::copy(s.begin(), s.end(), iter);
-s = "key2";
-encodeHeader(TSTR, foo.size(), iter);
-std::copy(s.begin(), s.end(), iter);
-encodeHeader(SIMPLE, TRUE, iter);
-```
-
-As the above example demonstrates, the styles can be mixed -- Note the
-creation and encoding of the inner Map using the fluent style.
-
-## Parsing
-
-CppBor also supports parsing of encoded CBOR data, with the same
-feature set as encoding.  There are two basic approaches to parsing,
-"full" and "stream"
-
-### Full parsing
-
-Full parsing means completely parsing a (possibly-compound) data
-item from a byte buffer.  The `parse` functions that do not take a
-`ParseClient` pointer do this.  They return a `ParseResult` which is a
-tuple of three values:
-
-* std::unique_ptr<Item> that points to the parsed item, or is nullptr
-  if there was a parse error.
-* const uint8_t* that points to the byte after the end of the decoded
-  item, or to the first unparseable byte in the event of an error.
-* std::string that is empty on success or contains an error message if
-  a parse error occurred.
-
-Assuming a successful parse, you can then use `Item::type()` to
-discover the type of the parsed item (e.g. MAP), and then use the
-appropriate `Item::as*()` method (e.g. `Item::asMap()`) to get a
-pointer to an interface which allows you to retrieve specific values.
-
-### Stream parsing
-
-Stream parsing is more complex, but more flexible.  To use
-StreamParsing, you must create your own subclass of `ParseClient` and
-call one of the `parse` functions that accepts it.  See the
-`ParseClient` methods docstrings for details.
-
-One unusual feature of stream parsing is that the `ParseClient`
-callback methods not only provide the parsed Item, but also pointers
-to the portion of the buffer that encode that Item.  This is useful
-if, for example, you want to find an element inside of a structure,
-and then copy the encoding of that sub-structure, without bothering to
-parse the rest.
-
-The full parser is implemented with the stream parser.
