// config_ns.h - written and placed in public domain by Jeffrey Walton
//               the bits that make up this source file are from the
//               library's monolithic config.h.

/// \file config_ns.h
/// \brief Library configuration file
/// \details <tt>config_ns.h</tt> provides defines for C++ and library
///  namespaces.
/// \details <tt>config.h</tt> was split into components in May 2019 to better
///  integrate with Autoconf and its feature tests. The splitting occurred so
///  users could continue to include <tt>config.h</tt> while allowing Autoconf
///  to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
///  its feature tests.
/// \note You should include <tt>config.h</tt> rather than <tt>config_ns.h</tt>
///  directly.

/// \namespace CryptoPP
/// \brief Crypto++ library namespace
/// \details Nearly all classes are located in the CryptoPP namespace. Within
///  the namespace, there are four additional namespaces.
///   <ul>
///     <li>Name - namespace for names used with NameValuePairs and documented
///         in argnames.h
///     <li>NaCl - namespace for NaCl test functions like crypto_box,
///         crypto_box_open, crypto_sign, and crypto_sign_open
///     <li>Donna - namespace for curve25519 library operations. The name was
///         selected due to use of Langley and Moon's curve25519-donna.
///     <li>Test - namespace for testing and benchmarks classes
///     <li>Weak - namespace for weak and wounded algorithms, like ARC4, MD5
///         and Pananma
///   </ul>
/// \since Crypto++ 3.0
