         This page documents library components that don't really fit in anywhere else.  
         They all basically follow the same conventions as 
         the rest of the library.   So to get a pipe for example you would need to write something 
         like <tt>typedef dlib::pipe::kernel_1a pipe_type;</tt> and from then on make your pipes like 
         <tt>pipe_type my_pipe(pipe_size);</tt>.  
         </p>

         <description>
                This object is an implementation of an allocator that conforms to the C++ standard 
                requirements for allocator objects.  The M template argument is one of the dlib
                memory manager objects and this allocator implementation will do all of its memory allocations
                using whatever dlib memory manager you supply.   

                  <p>
                Thus, using this allocator object you can use any of the dlib memory manager objects with
                the containers in the STL or with any other object that requires an STL style allocator object.
                  </p>

            This object provides a simple type safe mechanism to convert data

            This is a memory manager object which simply calls new and delete directly (i.e.
            it doesn't really do anything).  It is the default memory manager used by most 
            of the objects in dlib.

                This object represents some kind of stateless memory manager or memory pool.  
                Stateless means that all instances (instances of the same type that is) 
                of this object are identical and can be used interchangeably.  Note that 
                implementations are allowed to have some shared global state such as a 
                global memory pool.  This object is also thread safe.

                  This memory manager implementation allocates objects one at a time when there are
                  allocation requests.  Then when there is a deallocate request the returning object
                  is placed into a list of free blocks if that list has less than max_pool_size 
                  blocks in it.  Subsequent allocation requests will be serviced by drawing from the
                  free list whenever it isn't empty.  Array allocations, on the other hand, are not 
                  managed at all but are passed directly on to new and delete.
               <p>
                  When this object's max_pool_size template parameter is set to 0 it simply calls
                  new and delete directly and doesn't function as a memory pool.

                are managed.  So this object is just like kernel_2 but it also pools memory from 
                array allocations (chunk_size has no effect with respect to array allocations, each array
                is allocated one at a time). 
                Also, memory is not freed until this object is destructed.

                This object represents a general extension to any object.  This object gives any object which it extends 
                an integrated rmutex and rsignaler object.  The extended object will 
                then be able to be treated as if it was also a <a href="dlib/threads/rmutex_extension_abstract.h.html#rmutex">rmutex</a> and 
                <a href="dlib/threads/rsignaler_extension_abstract.h.html#rsignaler">rsignaler</a>.

               <description> 
                  This implementation has a single master thread that does all the waiting.
                  This master thread creates and dispatches threads to specific timer objects
                  when they need to run their action functions.  When a timer object isn't executing 
                  its action function then it doesn't have any thread allocated to it at all.  So
                  it is much more efficient than timer_kernel_1.

         <description>
      <p>
      This library comes with a command line driven regression test suite.  All the testing code
      is located in the <chm>dlib/test</chm><web><a href="dlib/test">dlib/test</a></web> folder.  If you want to build it and test the library on your 
      system you can use the makefile at <a href="dlib/test/makefile">dlib/test/makefile</a> (you may
      have to edit it to make it work on your system) or use the CMake CMakeLists.txt file at 
      <a href="dlib/test/CMakeLists.txt.html">dlib/test/CMakeLists.txt</a> to build it.  
      </p>
      <p>
         What you may find more useful however is the testing framework itself.  It uses a fairly simple
         and modular design.  Each test is contained in its own cpp file and when compiled into the
         program it automatically shows up in the list of tests to run.  If you want to use the
         testing framework all you need to do is add the files <a href="dlib/test/tester.h.html">dlib/test/tester.h</a>,
         <a href="dlib/test/tester.cpp.html">dlib/test/tester.cpp</a>, and <a href="dlib/test/main.cpp.html">dlib/test/main.cpp</a>
         to your project and then add cpp files that contain your tests (see 
         <a href="dlib/test/example.cpp.html">dlib/test/example.cpp</a> and 
         <a href="dlib/test/example_args.cpp.html">dlib/test/example_args.cpp</a> 
         for some examples).
      </p>
      <p>
         From the command line you can choose to run all the installed tests, enable or disable the loggers, 
         set various logging levels, specify how many times to run the tests, or pick just one or two tests
         to run at a time rather than the entire suite.
         The output of the program, that is, its return value from main() is the number of
         failed tests.  So if every test succeeds then it returns 0.
