  53. <p>All header files <code class="computeroutput">boost/contract/*.hpp</code> are independent from one another and can be included one-by-one to reduce the amount of code to compile from this library in user code (but this was measured to not make an appreciable difference in compile-time so <code class="computeroutput">boost/contract.hpp</code> can be included directly in most cases). Instead the headers <code class="computeroutput">boost/contract/core/*.hpp</code> are not independent from other library headers and they are automatically included by the <code class="computeroutput">boost/contract/*.hpp</code> headers (so the <code class="computeroutput">boost/contract/core/*.hpp</code> headers are usually not directly included by programmers).</p>
    54. 

  54. <p>All files under the <code class="computeroutput">boost/contract/detail/</code> directory, names within the <code class="computeroutput">boost::contract::detail</code> namespace, names prefixed by <code class="computeroutput">boost_contract_detail</code>... and <code class="computeroutput">BOOST_CONTRACT_DETAIL</code>... (in any namesapce, including user's code) are reserved for internal use of this library and should never be used directly by programmers.</p>
