-//    On many architectures the atomic instructions already act as

-//    This property is necessary for proper reference counting, since

-//
-//    Given:
-//
-//    - a mutable shared object OBJ;
-//    - two threads THREAD1 and THREAD2 each holding 
-//      a private smart_ptr object pointing to that OBJ.
-//
-//    t1: THREAD1 updates OBJ (thread-safe via some synchronization)
-//      and a few cycles later (after "unlock") destroys smart_ptr;
-//
-//    t2: THREAD2 destroys smart_ptr WITHOUT doing any synchronization 
-//      with respect to shared mutable object OBJ; OBJ destructors
-//      are called driven by smart_ptr interface...

+        <h2><a name="Introduction">Introduction</a></h2>
+        <p>The <STRONG>intrusive_ref_counter</STRONG> class template implements a reference counter for a derived
+            user's class that is intended to be used with <STRONG><a href="intrusive_ptr.html">intrusive_ptr</a></STRONG>.
+            The base class has associated <STRONG>intrusive_ptr_add_ref</STRONG> and <STRONG>intrusive_ptr_release</STRONG> functions
+            which modify the reference counter as needed and destroy the user's object when the counter drops to zero.</p>
+        <p>The class template is parameterized on <STRONG>DerivedT</STRONG> and <STRONG>CounterPolicyT</STRONG> parameters.
+            The first parameter is the user's class that derives from <STRONG>intrusive_ref_counter</STRONG>. This type
+            is needed in order to destroy the object correctly when there are no references to it left.</p>
+        <p>The second parameter is a policy that defines the nature of the reference counter.
+            Boost.SmartPtr provides two such policies: <STRONG>thread_unsafe_counter</STRONG> and <STRONG>thread_safe_counter</STRONG>. The former
+            instructs the <STRONG>intrusive_ref_counter</STRONG> base class to use a counter only suitable for a single-threaded use.
+            Pointers to a single object that uses this kind of reference counter must not be used in different threads. The latter policy
+            makes the reference counter thread-safe, unless the target platform doesn't support threading. Since in modern systems support for
+            threading is common, the default counter policy is <STRONG>thread_safe_counter</STRONG>.</p>

+<h2>Introduction</h2>
+<p>
+Originally the Boost function templates <code>allocate_shared</code> and
+<code>make_shared</code> were for efficient allocation of shared scalar
+objects only. There was a need to have efficient allocation of shared
+arrays. One criticism of class template <code>shared_array</code>
+was always the lack of a utility like <code>make_shared</code> that
+uses only a single allocation.
+</p>
+<p>
+The header files &lt;boost/smart_ptr/allocate_shared_array.hpp&gt; and
+&lt;boost/smart_ptr/make_shared_array.hpp&gt; provide function
+templates, overloads of <code>allocate_shared</code> and
+<code>make_shared</code> for array types, to address this need.
+<code>allocate_shared</code> uses a user-supplied allocator for
+allocation, while <code>make_shared</code> uses
+ <code>allocate_shared</code> with the Default Allocator.

+<dl>
+<dt><strong>Requires:</strong></dt>
+<dd><code>T</code> is of the form <code>E[N]</code> or
+<code>E[]</code>. <code>A</code> shall be an <em>Allocator</em>, as
+described in section 17.6.3.5 [Allocator requirements] of the C++
+Standard. The copy constructor and destructor of <code>A</code> shall
+not throw exceptions.</dd>
+<dt><strong>Effects:</strong></dt>
+<dd>Allocates storage for an object of type <code>E</code> (or
+<code>E[size]</code> when <code>T</code> is <code>E[]</code>, where
+<code>size</code> is determined from <code>args</code> as specified by
+the concrete overload). A copy of the allocator is used to allocate
+storage. The storage is initialized as specified by the concrete
+overload. If an exception is thrown, the functions have no effect.</dd>
+<dt><strong>Returns:</strong></dt>
+<dd>A <code>shared_ptr</code> instance that stores and owns the address
+of the newly allocated and constructed object.</dd>
+<dt><strong>Postconditions:</strong></dt>
+<dd><code>r.get() != 0</code> and <code>r.use_count() == 1</code>,
+where <code>r</code> is the return value.</dd>
+<dt><strong>Throws:</strong></dt>
+<dd>An exception thrown from <code>A::allocate()</code>, or from the
+initialization of the object.</dd>
+<dt><strong>Remarks:</strong></dt>
+<dd>
+<ul>
+<li>This implementation performs no more than one memory allocation.
+This provides efficiency to equivalent to an intrusive smart
+pointer.</li>
+<li>When an object of an array type <code>T</code> is specified to be
+initialized to a value of the same type <code>v</code>, this shall be
+interpreted to mean that each array element of the object is initialized
+to the corresponding element from <code>v</code>.</li>
+<li>When an object of an array type <code>T</code> is specified to be
+value-initialized, this shall be interpreted to mean that each array
+element of the object is value-initialized.</li>
+<li>Array elements are initialized in ascending order of their
+addresses.</li>
+<li>When a subobject of a scalar type <code>S</code> is specified to
+be initialized to a value <code>v</code>, <code>allocate_shared</code>
+shall perform this initialization via the expression
+<code>std::allocator_traits&lt;A&gt;::construct(b, p, v)</code>, where
+<code>p</code> points to storage suitable to hold an object of type
+<code>S</code> and <code>b</code> of is a copy of the allocator
+<code>a</code> passed to <code>allocate_shared</code> such that its
+<code>value_type</code> is <code>S</code>.</li>
+<li>When a subobject of scalar type <code>S</code> is specified to be
+value-initialized, <code>allocate_shared</code> shall perform this
+initialization via the expression
+<code>std::allocator_traits&lt;A&gt;::construct(b, p)</code>, where
+<code>p</code> points to storage suitable to hold an object
+of type <code>S</code> and <code>b</code> is a copy of the allocator
+<code>a</code> passed to <code>allocate_shared</code> such that its
+<code>value_type</code> is <code>S</code>.</li>
+<li>When a subobject of scalar type <code>S</code> is specified to be
+default-initialized, <code>allocate_shared_noinit</code> shall perform
+this initialization via the expression <code>::new(p) S</code>, where
+<code>p</code> has type <code>void*</code> and points to storage
+suitable to hold an object of type <code>S</code>.</li>
+<li>When the lifetime of the object managed by the return value ends,
+or when the initialization of an array element throws an exception,
+the initialized elements should be destroyed in the reverse order
+of their construction.</li>
