 Boost.Core
 ==========
 
-Boost.Core, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), is a collection of core utilities used by other Boost libraries.
+Boost.Core, part of collection of the [Boost C++ Libraries](http://github.com/boostorg), is a collection of core utilities used by other Boost libraries.
 The criteria for inclusion is that the utility component be:
 
 * simple,
 * used by other Boost libraries, and
 * not dependent on any other Boost modules except Core itself, Config, Assert, Static Assert, or Predef.

-
-[section Overview]
-
-The header `<boost/core/allocator_access.hpp>` provides the class and function
-templates to simplify allocator use. It provides the same functionality as the
-C++ standard library `std::allocator_traits` but with individual templates for
-each allocator feature.
-
-It also adds additional functionality for allocator aware exception safe
-construction and destruction of arrays.
-
-These facilities also simplify existing libraries by avoiding having to check
-for `BOOST_NO_CXX11_ALLOCATOR` and conditionally use `std::allocator_traits`.
-
-[endsect]
-
-[section Examples]
-
-The following example shows these utilities used in the definition of
-an allocator-aware container class:
-
-```
-template<class T, class A = boost::default_allocator<T> >
-class container
-    : boost::empty_value<typename boost::allocator_rebind<A, T>::type> {
-public:
-    typedef T value_type;
-    typedef A allocator_type;
-    typedef typename boost::allocator_size_type<A>::type size_type;
-    typedef typename boost::allocator_difference_type<A>::type difference_type;
-    typedef value_type& reference;
-    typedef const value_type& const_reference;
-    typedef typename boost::allocator_pointer<A>::type pointer;
-    typedef typename boost::allocator_const_pointer<A>::type const_pointer;
-    // ...
-};
-```
-
-In C++11 or above, aliases such as `boost::allocator_pointer_t<A>` can be used
-instead of `typename boost::allocator_pointer<A>::type`.
-
-The following example allocates storage for an array of `n` elements of `T`
-using an allocator `a` and constructs `T` elements in that storage. If any
-exception was thrown during construction of an element, the constructed
-elements are destroyed in reverse order.
-
-```
-template<class A>
-auto create(A& a, std::size_t n)
-{
-    auto p = a.allocate(n);
-    try {
-        boost::allocator_construct_n(a, boost::to_address(p), n);
-    } catch (...) {
-        a.deallocate(p, n);
-        throw;
-    }
-    return p;

-
-Under C++11, `endian` is defined as `enum class endian` as shown in the synopsis. Under C++03, its definition is

-{
-    little = see below,

-
-The values of `endian::big` and `endian::little` are distinct. `endian::native` is equal to `endian::big` on
-big endian platforms, equal to `endian::little` on little endian platforms, and a distinct value on platforms
-that are neither.
-
-Note that you should not rely on `little` and `big` having any specific values, because the C++20 standard
-leaves these unspecified.

-[section Revision History]
-
-[section Changes in 1.82.0]
-
-* Added [link core.snprintf `boost/core/snprintf.hpp`] header with portable definitions of `snprintf`, `vsnprintf` and
-  their `wchar_t` counterparts.
-* Deprecated `boost/core/is_same.hpp` and `boost::core::is_same`. The header will be removed in a future release.
-  Users are advised to use [@http://www.boost.org/doc/libs/release/libs/type_traits/doc/html/index.html Boost.TypeTraits]
-  or C++ standard library type traits instead.
-* Marked `boost::ref` member functions and associated methods with `noexcept`.
-* Marked `boost::swap` function with `noexcept`, depending on whether the type supports a non-throwing swap operation.
-* Added [link core.launder `boost::core::launder`], a portable implementation of `std::launder`.
-* Added [link core.alignof `BOOST_CORE_ALIGNOF`], a portable implementation of `alignof`.
-* Added [link core.max_align `boost::core::max_align_t`], a portable equivalent of `std::max_align_t`, and
-  `boost::core::max_align`, the alignment of `max_align_t`.
-* Added [link core.memory_resource `boost::core::memory_resource`], a portable equivalent of `std::pmr::memory_resource`
-  from C++17.
-* Added [link core.serialization `boost/core/serialization.hpp`], a collection of primitives allowing libraries to
-  implement Boost.Serialization support for their types without including a Serialization header and thereby making
-  their libraries depend on Serialization.
-* Added [link core.data `boost::data`], an implementation of `std::data`.
-* Added [link core.size `boost::size`], an implementation of `std::size`.
-* Updated `boost::span` to use `boost::data` which adds support for range
-  construction from an `std::initializer_list`.
-* Added [link core.identity `boost::identity`], an implementation of
-  `std::identity`. This facility has been moved from Boost.Functional.

-
-* [link core.empty_value `empty_value`] members are now marked as `constexpr`.

-* Bit manipulation utilities in [link core.bit `boost/core/bit.hpp`] now explicitly require unsigned integers on input.
-  ([@https://github.com/boostorg/core/issues/129 #129])
-* `bit_width` now returns `int` instead of a value of the input argument type. This follows the
-  resolution of [@https://cplusplus.github.io/LWG/issue3656 LWG3656].
-
-[endsect]

-[section Changes in 1.80.0]
-
-* In [link core.allocator_access `boost/core/allocator_access.hpp`], added detection of `construct` and `destroy`
-  members of an allocator.
-* `boost/core/alloc_construct.hpp` header is now deprecated and will be removed in a future release. Its functionality
-  was moved to [link core.allocator_access `boost/core/allocator_access.hpp`]. In particular, new methods
-  `allocator_construct_n` and `allocator_destroy_n` were added for allocating and destroying arrays.
-* Worked around MSVC bug that failed to compile [link core.span `span`] in C++17 mode when Boost.Range headers were included.
-  ([@https://github.com/boostorg/core/issues/105 #105], [@https://github.com/boostorg/core/pull/115 PR#115])

-* In [link core.pointer_traits `pointer_traits`], pointer rebinding now supports C++03 compilers.

-[section Changes in 1.79.0]
-
-* Added `boost::allocator_traits`, an implementation of `std::allocator_traits`.
-* Made `boost::pointer_traits` SFINAE friendly.
-* `boost/iterator.hpp` is deprecated and will be removed in a future release. The header defines the
-  `boost::iterator` template, which is equivalent to `std::iterator` in the `<iterator>` header. However,
-  since `std::iterator` is itself deprecated in C++17, users are advised to remove the use of `boost::iterator`
-  or `std::iterator` from their code.
-* Added `boost::core::verbose_terminate_handler`, a utility function intended
-  to be passed to `std::set_terminate` that prints information about the
-  uncaught exception to `stderr`.
-

-[section Changes in 1.78.0]

-
-* Implemented the allocator access utilities which provide a replacement for `allocator_traits`

-
-* Added functions `alloc_construct`, `alloc_construct_n`, `alloc_destroy`, and `alloc_destroy_n`

-  destruction of objects and arrays.
-* Added constexpr functions `first_scalar` in `<boost/core/first_scalar.hpp>` for obtaining a pointer
-  to the first scalar element of an array. Given a pointer of type `T*` they return a pointer of type
-  `remove_all_extents_t<T>*`.
-* Added class template `noinit_adaptor` in `<boost/core/noinit_adaptor.hpp>` which is an allocator adaptor
-  that converts any allocator into one whose `construct(ptr)` performs default initialization via placement
-  `new`, and whose `destroy(ptr)` invokes the `value_type` destructor directly.
-* Added class template `default_allocator` in `<boost/core/default_allocator.hpp>`, which can serve as a minimal
-  default allocator that has interface similar to C++20 `std::allocator`, supports configurations with disabled
-  exceptions and does not have `std` as an associated namespace. The allocator uses `operator new` and
-  `operator delete` for allocation.
-* In `<boost/core/uncaught_exceptions.hpp>` header, added workarounds for better compatibility with QNX SDP 7.0
-  when libc++/libc++abi libraries are used.
-* The `<boost/detail/sp_typeinfo.hpp>` header is now marked as deprecated and will be removed in a future release.
-  `<boost/core/typeinfo.hpp>` should be used instead.

-* Implemented `boost::quick_exit` to provide the C++11 standard library facility `std::quick_exit` functionality.
-* Reduced the number of statics in Lightweight Test, and employ lighter abort behavior for MSVC compilers upon
-  failure to call `boost::report_errors`.
-

-The header <boost/core/default_allocator.hpp> provides the class template
-`boost::default_allocator` to serve as a minimal default allocator that:

-* Like C++2a's `std::allocator`, does not provide members such as `construct()`
-and `destroy()` to be eligible for optimizations by allocator-aware code that
-detects the absence of these members to provide more optimal construction.
-* Supports `BOOST_NO_EXCEPTIONS` in allocation.

-[section Overview]
-
-The header <boost/core/exchange.hpp> provides the function template
-`boost::exchange` which is an implementation of the `std::exchange`
-function introduced in C++14. `boost::exchange(o, v)` replaces the
-value of `o` with `v` and returns the old value of `o`.
-
-[endsect]
-
-[section Examples]
-
-The following example shows `boost::exchange` used to simplify the
-implementation of a move constructor.
-
-```
-Node(Node&& other)
-  : head_(boost::exchange(other.head_, nullptr))
-  , tail_(boost::exchange(other.tail_, nullptr)) { }
-```

-  template<class T, class U = T>
-  constexpr T exchange(T& t, U&& u);
-}
-```
-[section Functions]
-
-[*`template<class T, class U = T> constexpr T exchange(T& t, U&& u);`]

-The header <boost/core/first_scalar.hpp> provides the function templates
-`boost::first_scalar` that can be used to obtain a pointer to the first scalar
-element of an array. Given a pointer of type `T*` they return a pointer of

-and whose `destroy(ptr)` invokes `value_type` destructor directly.

-The following example shows use of this allocator adaptor to achieve default

-The `allocate_shared_noinit` function templates are now implemented simply
-using `allocate_shared` with `noinit_adaptor`.

-The header <boost/core/nvp.hpp> provides the class template `boost::nvp` that
-pairs a name (`const char*`) with the address of a value (`T*`). It is the new
-implementation of the NVP type previously provided by the Boost Serialization
-library. This type now lives in the Core library so that other Boost libraries
-can support named value serialization without taking a dependency on the
-Serialization library.

-The header `<boost/core/snprintf.hpp>` provides portable definition of [@https://en.cppreference.com/w/c/io/fprintf `snprintf`],
-`vsnprintf` and their corresponding `wchar_t` counterparts. On a platform that supports these functions in the standard library,
-these definitions are equivalent to the standard functions. On other platforms (mainly, older MSVC versions) these functions
-are emulated through non-standard functions that have similar behavior.
-
-Depending on the standard library, certain implementation differences are exposed to the user:
-
-* Any non-standard behavior with respect to string format description are not hidden by the emulation.
-* Returned value of `boost::core::snprintf` in case if the output buffer is too small may not be equal to the number of characters
-  that would have been written if the buffer was large enough. It is, however, equal or larger than the buffer size,
-  which still allows the caller to detect the buffer overflow condition. The formatted output is still properly null-terminated

-[section Overview]
-
-This header <boost/core/span.hpp> provides class template `span`, which is a
-view over a sequence of objects. It implements the C++20 standard library
-`std::span` facility. This implementation supports C++11 and higher.
-
-In addition to referencing the sequence of objects, the span knows the count of
-objects. There are two kinds of spans:
-
-* Dynamic size (`span<T>` or `span<T, dynamic_extent>`)
-* Static size (`span<T, N>`)
-
-Dynamic size spans have a count that can be a value known at run time. Static
-size spans have a count that must be known at compile time.
-

-
-[section Examples]
-
-The following snippet shows a function to compute a SHA1 hash whose parameters
-and return type use spans.
-
-```
-auto sha1(boost::span<const unsigned char> input,
-    boost::span<unsigned char, SHA_DIGEST_LENGTH> ouput)
-{
-    SHA_CTX context;
-    SHA1_Init(&context);
-    SHA1_Update(&context, input.data(), input.size());
-    SHA1_Final(output.data(), &context);
-    return output;

-[section Header <boost/core/string_view.hpp>]
-
-The header `<boost/core/string_view.hpp>` defines `boost::core::string_view`,
-a portable and interoperable implementation of `std::string_view`.
-
-Unlike `boost::string_view`, `boost::core::string_view` has implicit
-conversions from and to `std::string_view`, which allows Boost libraries that
-support C++11/C++14 to use it in interfaces without forcing users to forgo the
-use of `std::string_view` in their code.

-throwing an exception from a destructor can terminate the program.
-
-Unfortunately, the function cannot be implemented on every pre-C++17 compiler, although the most commonly
-used compilers are supported. When the compiler does not provide the necessary functionality,
-`boost::core::uncaught_exceptions` returns a non-zero value if at least one exception is pending (i.e. not
-necessarily the number of pending exceptions), and `BOOST_CORE_UNCAUGHT_EXCEPTIONS_EMULATED` macro
-is defined.

-
-The header `<boost/core/verbose_terminate_handler.hpp>` defines
-the function `void boost::core::verbose_terminate_handler()`. Its
-purpose is to be set as a terminate handler as in
-```
-    std::set_terminate( boost::core::verbose_terminate_handler );
-```
-
-When invoked, the function prints information about the current
-uncaught exception to `stderr` and then calls `std::abort`.

-// MinGW GCC 4.4 seem to not work the same way the newer GCC versions do. As a result, __cxa_get_globals based implementation will always return 0.
-// Just disable it for now and fall back to std::uncaught_exception().
-// On AIX, xlclang++ does have cxxabi.h but doesn't have __cxa_get_globals (https://github.com/boostorg/core/issues/78).

-// At least on MinGW and Linux, only GCC since 4.7 declares __cxa_get_globals() in cxxabi.h. Older versions of GCC do not expose this function but it's there.
-// On OpenBSD, it seems, the declaration is also missing.
-// Note that at least on FreeBSD 11, cxxabi.h declares __cxa_get_globals with a different exception specification, so we can't declare the function unconditionally.
-// On Linux with clang and libc++ and on OS X, there is a version of cxxabi.h from libc++abi that doesn't declare __cxa_get_globals, but provides __cxa_uncaught_exceptions.
-// The function only appeared in version _LIBCPPABI_VERSION >= 1002 of the library. Unfortunately, there are linking errors about undefined reference to __cxa_uncaught_exceptions
-// on Ubuntu Trusty and OS X, so we avoid using it and forward-declare __cxa_get_globals instead.
-// On QNX SDP 7.0 (QCC 5.4.0), there are multiple cxxabi.h, one from glibcxx from gcc and another from libc++abi from LLVM. Which one is included will be determined by the qcc
-// command line arguments (-V and/or -Y; http://www.qnx.com/developers/docs/7.0.0/#com.qnx.doc.neutrino.utilities/topic/q/qcc.html). The LLVM libc++abi is missing the declaration
-// of __cxa_get_globals but it is also patched by QNX developers to not define _LIBCPPABI_VERSION. Older QNX SDP versions, up to and including 6.6, don't provide LLVM and libc++abi.
