+`std::span` implementation for C++11 and later
+==============================================
+
+This repository contains a single-header implementation of C++20's `std::span`,
+conforming to the C++20 committee draft.
+It is compatible with C++11, but will use newer language features if they
+are available.
+
+It differs from the implementation in the [Microsoft GSL](https://github.com/Microsoft/GSL/)
+in that it is single-header and does not depend on any other GSL facilities. It
+also works with C++11, while the GSL version requires C++14.
+
+Usage
+-----
+
+The recommended way to use the implementation simply copy the file `span.hpp`
+from `include/tcb/` into your own sources and `#include` it like
+any other header. By default, it lives in namespace `tcb`, but this can be
+customised by setting the macro `TCB_SPAN_NAMESPACE_NAME` to an appropriate string
+before `#include`-ing the header -- or simply edit the source code.
+
+The rest of the repository contains testing machinery, and is not required for
+use.
+
+Compatibility
+-------------
+
+This implementation requires a conforming C++11 (or later) compiler,  and is tested as far
+back as GCC 5, Clang 3.5 and MSVC 2015 Update 3. Older compilers may work, but this is not guaranteed.
+
+Documentation
+-------------
+
+Documentation for `std::span` is available [on cppreference](https://en.cppreference.com/w/cpp/container/span).

+### Bounds Checking ###
+
+This implementation of `span` includes optional bounds checking, which is handled
+either by throwing an exception or by calling `std::terminate()`.
+
+The default behaviour with C++14 and later is to check the macro `NDEBUG`:
+if this is set, bounds checking is disabled. Otherwise, `std::terminate()` will
+be called if there is a precondition violation (i.e. the same behaviour as
+`assert()`). If you wish to terminate on errors even if `NDEBUG` is set, define
+the symbol `TCB_SPAN_TERMINATE_ON_CONTRACT_VIOLATION` before `#include`-ing the
+header.
+
+Alternatively, if you want to throw on a contract violation, define
+`TCB_SPAN_THROW_ON_CONTRACT_VIOLATION`. This will throw an exception of an
+implementation-defined type (deriving from `std::logic_error`), allowing
+cleanup to happen. Note that defining this symbol will cause the checks to be
+run even if `NDEBUG` is set.
+
+Lastly, if you wish to disable contract checking even in debug builds,
+`#define TCB_SPAN_NO_CONTRACT_CHECKING`.
+
+Under C++11, due to the restrictions on `constexpr` functions, contract checking
+is disabled by default even if `NDEBUG` is not set. You can change this by
+defining either of the above symbols, but this will result in most of `span`'s
+interface becoming non-`constexpr`.
+
+### `constexpr` ###
+
+This implementation is fully `constexpr` under C++17 and later. Under earlier
+versions, it is "as `constexpr` as possible".
+
+Note that even in C++17, it is generally not possible to declare a `span`
+as non-default constructed `constexpr` variable, for the same reason that you
+cannot form a `constexpr` pointer to a value: it involves taking the address of
+a compile-time variable in a way that would be visible at run-time.
+You can however use a `span` freely in a `constexpr` function. For example:
+
+```cpp
+// Okay, even in C++11
+constexpr std::ptrdiff_t get_span_size(span<const int> span)
+{
+    return span.size();
+}
+
+constexpr int arr[] = {1, 2, 3};
+constexpr auto size = get_span_size(arr); // Okay
+constexpr span<const int> span{arr}; // ERROR -- not a constant expression
+constexpr const int* p = arr; // ERROR -- same
+```
+
+Constructor deduction guides are provided if the compiler supports them. For
+older compilers, a set of `make_span()` functions are provided as an extension
+which use the same logic, for example:
+
+   ```cpp
+   constexpr int c_array[] = {1, 2, 3};
+   std::array<int, 3> std_array{1, 2, 3};
+   const std::vector<int> vec{1, 2, 3};
+
+   auto s1 = make_span(c_array);   // returns span<const int, 3>
+   auto s2 = make_span(std_array); // returns span<int, 3>
+   auto s3 = make_span(vec);       // returns span<const int, dynamic_extent>
+   ```

+  implementation from which `std::span` was born.
+  
+* [martinmoene/span_lite](https://github.com/martinmoene/span-lite): An
+  alternative implementation which offers C++98 compatibility.

+*************************************************************************
+**
+** This file demonstrates how to create a table-valued-function that
+** returns the values in a C-language array.
+** Examples:
+**
+**      SELECT * FROM carray($ptr,5)
+**
+** The query above returns 5 integers contained in a C-language array
+** at the address $ptr.  $ptr is a pointer to the array of integers.
+** The pointer value must be assigned to $ptr using the
+** sqlite3_bind_pointer() interface with a pointer type of "carray".
+** For example:
+**
+**    static int aX[] = { 53, 9, 17, 2231, 4, 99 };
+**    int i = sqlite3_bind_parameter_index(pStmt, "$ptr");
+**    sqlite3_bind_pointer(pStmt, i, aX, "carray", 0);
+**
+** There is an optional third parameter to determine the datatype of
+** the C-language array.  Allowed values of the third parameter are
+** 'int32', 'int64', 'double', 'char*'.  Example:
+**
+**      SELECT * FROM carray($ptr,10,'char*');
+**
+** The default value of the third parameter is 'int32'.
+**
+** HOW IT WORKS
+**
+** The carray "function" is really a virtual table with the
+** following schema:
+**
+**     CREATE TABLE carray(
+**       value,
+**       pointer HIDDEN,
+**       count HIDDEN,
+**       ctype TEXT HIDDEN
+**     );
+**
+** If the hidden columns "pointer" and "count" are unconstrained, then 
+** the virtual table has no rows.  Otherwise, the virtual table interprets
+** the integer value of "pointer" as a pointer to the array and "count"
+** as the number of elements in the array.  The virtual table steps through
+** the array, element by element.
