+Our discussion will focus on archives used for saving as the hierarchy is exactly analogous
+for archives used for loading data.
+
+<h4>Minimum Requirments</h4>
+
+The simplest class which will model the <a href="archives.html"><strong>Archive</strong></a> concept specifies the functions that a
+class will look like:
+
+<pre><code>
+#include &lt;cstddef&gt; // std::size_t
+//////////////////////////////////////////////////////////////
+// class trivial_oarchive
+class trivial_oarchive {
+public:
+    //////////////////////////////////////////////////////////
+    // public interface used by programs that use the
+    // serialization library
+    typedef boost::mpl::bool_&lt;true&gt; is_saving; 
+    typedef boost::mpl::bool_&lt;false&gt; is_loading;
+    template&lt;class T&gt; register_type(){}
+    template&lt;class T&gt; trivial_oarchive & operator&lt;&lt;(const T & t){
+        return *this;
+    }
+    template&lt;class T&gt; trivial_oarchive & operator&(const T & t){
+        return *this &lt;&lt; t;
+    }
+    void save_binary(void *address, std::size_t count){};
+};
+</code></pre>
+The simplest possible input archive class is analogous to the above.
+In the following discussion, only output archives will be addressed.
+Input archives are exactly symmetrical to output archives.
+<p>
+This archive will compile and execute with any types which implement the
+<a href="serialization.html"><strong>Serializable</strong></a> concept.
+For an example see
+<a href="../example/demo_trivial_archive.cpp" target="demo_trivial_archive">
+<code style="white-space: normal">demo_trivial_archive.cpp</code></a>.
+Of course this program won't produce any output as it is.  But it provides
+the starting point for a simple class which can be used to log formated
+output.  See the implementation of a <a href="simple_log.html">simple
+log archive</a> to how this has been done.
+
+<h3><a name="implementation">More Useful Archive Classes</a></h3>
+The above example is fine as far as it goes.  But it doesn't implement
+useful features such as serialization of pointers, class versioning
+and others. This library implements a family of full featuared archive
+classes appropriate for a variety of purposes.  
+
 <p>
 Our archives have been factored in to a tree of classes in order to minimize
 repetition of code.  This is shown in the accompanying 
 <a target="class_diagram" href="class_diagram.html">class diagram</a>.
-All input archives should be derived from the following template:
-<pre><code>
-template&lt;class Archive&gt;
-detail::common_iarchive;
-</code></pre>
-<h4>Minimum Requirments</h4>
-An instance of the this template handles all the "bookkeeping" associated
-with serialization. In order to be a functional only the following additional
-functions <strong>must</strong> be defined:
-<dl>
-<dt><h4><code>void load(T &t);</code></h4></dt>
-<dd>
-This function must be implemented for all primitive data types.  This can be
-accomplished through the use of a member template or explict declarations
-for all prmititive types.
-</dd>

-<dt><h4><code>void load_binary(void *address, std::size_t size);</code></h4></dt>
-<dd>
-This function should <code style="white-space: normal">size</code> bytes from the archive, and 
-copy them in to memory starting at address <code style="white-space: normal">address</code>.
-</dd>
-
-<dt><h4><code>friend class boost::archive::load_access;</code></h4></dt>
-<dd>
-In addition, such a class <strong>must</strong> provide a the following
-friend declaration grant access to the core serialization library to the functions
-of this class.
-</dd>
-
-</dl>
-
-So, the most trivial implementation of an input archive would look like this:

-<h3>Portable Binary Archives</h3>
+<h3>Log Archive</h3>
 It may happen that one wants to create a new archive class by derivation from one
 of the included ones. Included is a sample program that shows how to derive a 
 new archive from one of the ones included with the library.  The first example is
-<a href="../example/demo_portable_archive.cpp" target="demo_portable_archive_cpp">demo_portable_archive.cpp</a>.
-This binary archive save/loads integers in a portable format.  To this end
-it is derived from the native binary archive and the save/load functions for
-integers are overridden with special versions which convert to big endian
-format if necessary.  It also implements an exception for the case where an
-integer saved on one platform is too large for the platform which is loading
-the archive.  This example doesn't address floating point types.
-This examples illustrates several issues that have to be addressed when doing
-something like this.  The discussion below refers to the output archive only but it
-applies equally to input archives as well.
+<a href="../example/demo_log.cpp" target="demo_log_cpp">
+demo_log.cpp</a>.
+<p>
+This derivation from the xml archive writes output in xml without the extra
+information required to read the data back into the application.  It might be
+used to export one's data as simple xml for other applications or for logging
+data while debugging.
+<p>
+To this end it is derived from the included xml archive and the save functions for
+some types are specialized for this application.  
+<p>
+The serialization library is
+implemented using the <b>C</b>uriously <b>R</b>ecurring <b>T</b>emplate 
+<b>P</b>attern (<b>CRTP</b>).  Also, all common code is factored out into
+separate modules to minimize code repetition. This makes derivation from

-<h3>Fast Binary Archives</h3>
-The second example 
-<a href="../example/demo_fast_archive.cpp" target="demo_fast_archive_cpp">demo_fast_archive.cpp</a>.
-is similar to the first one.  The difference is that it intercepts the serialization before
-the default serialization is invoked.  In this case we want to replace the default
-serialization of C arrays of integers with a faster one.  The default version
-will invoke serialization of each element of the array.  If its an array of
-integers, and we're not concerned with the archive being portable to another platform
-we can just save/load the whole array as a binary string of bytes.  This should
-be faster than the default element by element method.
-<p>
-The same considerations that applied when overriding the the save/load of primitives
-above apply here, and the code is very similar.

+Each type to be managed by the system must be

+one would include the following code:
+
+<code style="white-space: normal"><pre>
+namespace boost {
+namespace serialization {
+template
+struct extended_type_info_typeid&gt;T&gt;;
+template
+struct extended_type_info_typeid&gt;const T&gt;;
+} // serialization
+} // boost
+</pre></code>
+
+For those using the serialization library, this step can be skipped
+as it is done automatically.  The serialization library includes
+the macro:
+
+<code style="white-space: normal"><pre>
+BOOST_CLASS_TYPE_INFO(
+    my_type, 
+    extended_type_info_typeid&gt;my_class&gt;
+)
+</pre></code>
+
+which is used to specify which <code>extended_type_info</code> system is to 
+be used for a given type.
+<p>
+<code>extended_type_info</code> includes a facility for constructing
+instances of types without knowing what the exact types are. This is done
+with the function 
+<code>
+virtual void * extended_type_info::construct(unsigned int count = 0, ...) const;
+</code>
+. For example:
+<br>
+<code><pre>
+struct base {
+...
+};
+struct derived : public base {
+...
+};
+...
+extended_type_info *eti = extended_type_info::find("my_class")
+base * b = eti->construct(...);
+</pre></code>
+<br>
+The <code>construct</code> takes an argument count and up to
+four parameters of any type.  The arguments are passed to the
+constructor of "my_class".

+
+<h2><a name="functionobject"></a>Serializing a Function Object</h2>
+An example on how to serialize a function object.  I believe this
+could be done by serializing pointer to the object in question.  Since
+the Serialization library resurrects pointer of the correct type
+this should be easily implementable.
+<p>
+If a group of function objects were all derived from the
+same polymorphic base class - perhaps via multiple inheritance,
+the the function object effectively becomes a "variable" which
+encapsulates code.
+<p>
+This case study would show how to do this.
+
+<h2><a name="archiveadaptor"></a>Archive Adaptors</h2>
+
+Often users want to add their own special functionality to an
+existing archive.  Examples of this are performance enhancements
+for specific types, Adjustment of output syntax for xml archives,
+and logging/debug output as archives are written and/or read.
+If this functionalty is implemented as an "adaptor" template
+which takes the base class as a template argument, such functionality
+appended to any archive for which that funtionality makes sense.
+For example, an adaptor for generating an xml schema could be
+appended to both wide narrow character versions of xml archives.
+<p>
+This case study would show how to make a useful archive adaptor.
+
+<h2><a name="archivehelper"></a>Archive Helpers</h2>
+Some types are not serializable as they stand.  That is - they
+do not fullfill the requirements of the "Serializable Concept".
+The iconic example of this is boost::shared_ptr.  Sometimes
+these types could be made serializable by adding code inside
+the library.  Of course, doing that would create a lifetime
+of unpaid employment for the library author. Rather than
+adding a bunch of special code to the library itself, this
+code can packaged as a "helper" or "mix-in" class.  Then
+a new archive is derived from both the "base" archive class
+AND the "helper" class.  This is how boost::shared_ptr
+has been implemented.
+<p>
+It would also be possible to make a "generic runtime helper"
+which would effectively extend the API of the library.  Previously
+the library included such a helper class.  It was removed
+in favor of the current implementation.  But this functionality
+should be added back in with another adaptor which would
+become part of the library.

+
+ This table describes the call tree of the program, and was sorted by
+ the total amount of time spent in each function and its children.
+
+ Each entry in this table consists of several lines.  The line with the
+ index number at the left hand margin lists the current function.
+ The lines above it list the functions that called this function,
+ and the lines below it list the functions this one called.
+ This line lists:
+     index	A unique number given to each element of the table.
+		Index numbers are sorted numerically.
+		The index number is printed next to every function name so
+		it is easier to look up where the function in the table.
+
+     % time	This is the percentage of the `total' time that was spent
+		in this function and its children.  Note that due to
+		different viewpoints, functions excluded by options, etc,
+		these numbers will NOT add up to 100%.
+
+     self	This is the total amount of time spent in this function.
+
+     children	This is the total amount of time propagated into this
+		function by its children.
+
+     called	This is the number of times the function was called.
+		If the function called itself recursively, the number
+		only includes non-recursive calls, and is followed by
+		a `+' and the number of recursive calls.
+
+     name	The name of the current function.  The index number is
+		printed after it.  If the function is a member of a
+		cycle, the cycle number is printed between the
+		function's name and the index number.
+
+
+ For the function's parents, the fields have the following meanings:
+
+     self	This is the amount of time that was propagated directly
+		from the function into this parent.
+
+     children	This is the amount of time that was propagated from
+		the function's children into this parent.
+
+     called	This is the number of times this parent called the
+		function `/' the total number of times the function
+		was called.  Recursive calls to the function are not
+		included in the number after the `/'.
+
+     name	This is the name of the parent.  The parent's index
+		number is printed after it.  If the parent is a
+		member of a cycle, the cycle number is printed between
+		the name and the index number.
+
+ If the parents of the function cannot be determined, the word
+ `<spontaneous>' is printed in the `name' field, and all the other
+ fields are blank.
+
+ For the function's children, the fields have the following meanings:
+
+     self	This is the amount of time that was propagated directly
+		from the child into the function.
+
+     children	This is the amount of time that was propagated from the
+		child's children to the function.
+
+     called	This is the number of times the function called
+		this child `/' the total number of times the child
+		was called.  Recursive calls by the child are not
+		listed in the number after the `/'.
+
+     name	This is the name of the child.  The child's index
+		number is printed after it.  If the child is a
+		member of a cycle, the cycle number is printed
+		between the name and the index number.
+
+ If there are any cycles (circles) in the call graph, there is an
+ entry for the cycle-as-a-whole.  This entry shows who called the
+ cycle (as parents) and the members of the cycle (as children.)
+ The `+' recursive calls entry shows the number of function calls that
+ were internal to the cycle, and the calls entry for each member shows,
+ for that member, how many times it was called from other members of
+ the cycle.

-<h2><a name="trap"></a>Compile time trap when saving a non-const value</h2>
-</p>
-The following code will fail to compile.  The failure will occur on a line with a
-<code style="white-space: normal">BOOST_STATIC_ASSERT</code>.  
-Here, we refer to this as a compile time trap.
-<code style="white-space: normal"><pre>
-T t;
-ar &lt;&lt; t;
-</pre></code>
-
-unless the tracking_level serialization trait is set to "track_never". The following
-will compile without problem:
-
-<code style="white-space: normal"><pre>
-const T t
-ar &lt;&lt; t;
-</pre></code>
-
-Likewise, the following code will trap at compile time:
-
-<code style="white-space: normal"><pre>
-T * t;
-ar >> t;
-</pre></code>
-
-if the tracking_level serialization trait is set to "track_never".
-<p>
-
-This behavior has been contraversial and may be revised in the future. The criticism 
-is that it will flag code that is in fact correct and force users to insert
-<code style="white-space: normal">const_cast</code>. My view is that:
-<ul>
-  <li>The trap is useful in detecting a certain class of programming errors.
-  <li>Such errors would otherwise be difficult to detect.
-  <li>The incovenience caused by including this trap is very small in relation
-  to its benefits.
-</ul>
-
-The following case illustrates my position.  It was originally used as an example in the
-mailing list by Peter Dimov.
-
-<code style="white-space: normal"><pre>
-class construct_from 
-{ 
-    ... 
-}; 
-
-void main(){ 
-    ... 
-    Y y; 
-    construct_from x(y); 
-    ar &lt;&lt; x; 
-} 
-</pre></code>
-
-Suppose that there is no trap as described above.
-<ol>
-  <li>this example compiles and executes fine. No tracking is done because 
-  construct_from has never been serialized through a pointer. Now some time 
-  later, the next programmer(2) comes along and makes an enhancement. He 
-  wants the archive to be sort of a log. 
-
-<code style="white-space: normal"><pre>
-void main(){ 
-    ... 
-    Y y; 
-    construct_from x(y); 
-    ar &lt;&lt; x; 
-    ... 
-    x.f(); // change x in some way 
-   ... 
-    ar &lt;&lt; x 
-} 
-</pre></code>
-  <p>
-  Again no problem. He gets two different of copies in the archive, each one is different. 
-  That is he gets exactly what he expects and is naturally delighted. 
-  <p>
-  <li>Now sometime later, a third programmer(3) sees construct_from and says - 
-  oh cool, just what I need. He writes a function in a totally disjoint 
-  module. (The project is so big, he doesn't even realize the existence of 
-  the original usage) and writes something like: 
-
-<code style="white-space: normal"><pre>
-class K { 
-    shared_ptr &lt;construct_from&gt; z; 
-    template &lt;class Archive&gt; 
-    void serialize(Archive & ar, const unsigned version){ 
-        ar &lt;&lt; z; 
-    } 
-}; 
-</pre></code>
-
-  <p>
-  He builds and runs the program and tests his new functionality. It works 
-  great and he's delighted. 
-  <p>
-  <li>Things continue smoothly as before.  A month goes by and it's 
-  discovered that when loading the archives made in the last month (reading the 
-  log). Things don't work. The second log entry is always the same as the 
-  first. After a series of very long and increasingly acrimonius email exchanges, 
-its discovered 
-  that programmer (3) accidently broke programmer(2)'s code .This is because by 
-  serializing via a pointer, the "log" object now being tracked.  This is because
-  the default tracking behavior is "track_selectively".  This means that class
-  instances are tracked only if they are serialized through pointers anywhere in
-  the program. Now multiple saves from the same address result in only the first one 
-  being written to the archive. Subsequent saves only add the address - even though the 
-  data might have been changed.  When it comes time to load the data, all instances of the log record show the same data.
-  In this way, the behavior of a functioning piece of code is changed due the side
-  effect of a change in an otherwise disjoint module.
-  Worse yet, the data has been lost and cannot not be now recovered from the archives.
-  People are really upset and disappointed with boost (at least the serialization system).
-  <p>
-  <li>
-  After a lot of investigation, it's discovered what the source of the problem
-  and class construct_from is marked "track_never" by including:
-<code style="white-space: normal"><pre>
-BOOST_SERIALIZATION_TRACKING(construct_from, track_never) 
-</pre></code>
-  <li>Now everything works again. Or - so it seems.
-  <p>
-  <li><code style="white-space: normal">shared_ptr&lt;construct_from&gt;</code>
-is not going to have a single raw pointer shared amongst the instances. Each loaded 
-<code style="white-space: normal">shared_ptr&lt;construct_from&gt;</code> is going to 
-have its own distinct raw pointer. This will break 
-<code style="white-space: normal">shared_ptr</code> and cause a memory leak.  Again,
-The cause of this problem is very far removed from the point of discovery.  It could 
-well be that the problem is not even discovered until after the archives are loaded.
-Now we not only have difficult to find and fix program bug, but we have a bunch of
-invalid archives and lost data.
-</ol>
-
-Now consider what happens when the trap is enabled:. 
-
-<ol>
-  <p>
-  <li>Right away, the program traps at 
-<code style="white-space: normal"><pre>
-ar &lt;&lt; x; 
-</pre></code>
-  <p>
-  <li>The programmer curses (another %^&*&* hoop to jump through). If he's in a 
-  hurry (and who isn't) and would prefer not to <code style="white-space: normal">const_cast</code>
-  - because it looks bad.  So he'll just make the following change an move on. 
-<code style="white-space: normal"><pre>
-Y y; 
-const construct_from x(y); 
-ar &lt;&lt; x; 
-</pre></code>
-  <p>
-  Things work fine and he moves on. 
-  <p>
-  <li>Now programer (2) wants to make his change - and again another 
-  annoying const issue; 
-<code style="white-space: normal"><pre>
-Y y; 
-const construct_from x(y); 
-... 
-x.f(); // change x in some way ; compile error f() is not const 
-... 
-ar &lt;&lt; x 
-</pre></code>
-  <p>
-  He's mildly annoyed now he tries the following: 
-  <ul>
-    <li>He considers making f() a const - but presumable that shifts the const 
-    error to somewhere else. And his doesn't want to fiddle with "his" code to 
-    work around a quirk in the serializaition system 
-    <p>
-    <li>He removes the <code style="white-space: normal">const</code>
-    from <code style="white-space: normal">const construct_from</code> above - damn now he 
-    gets the trap. If he looks at the comment code where the 
-    <code style="white-space: normal">BOOST_STATIC_ASSERT</code>
-    occurs, he'll do one of two things 
-    <ol>
-      <p>
-      <li>This is just crazy. Its making my life needlessly difficult and flagging 
-      code that is just fine. So I'll fix this with a <code style="white-space: normal">const_cast</code>
-      and fire off a complaint to the list and mabe they will fix it. 
-      In this case, the story branches off to the previous scenario.
-      <p>
-      <li>Oh, this trap is suggesting that the default serialization isn't really 
-      what I want. Of course in this particular program it doesn't matter. But 
-      then the code in the trap can't really evaluate code in other modules (which 
-      might not even be written yet). OK, I'll add the following to my 
-      construct_from.hpp to solve the problem. 
-<code style="white-space: normal"><pre>
-BOOST_SERIALIZATION_TRACKING(construct_from, track_never) 
-</pre></code>
-    </ol>
-  </ul>
-  <p>
-  <li>Now programmer (3) comes along and make his change. The behavior of the 
-  original (and distant module) remains unchanged because the 
-  <code style="white-space: normal">construct_from</code> trait has been set to 
-  "track_never" so he should always get copies and the log should be what we expect.
-  <p>
-  <li>But now he gets another trap - trying to save an object of a 
-  class marked "track_never" through a pointer. So he goes back to 
-  construct_from.hpp and comments out the 
-  <code style="white-space: normal">BOOST_SERIALIZATION_TRACKING</code> that 
-  was inserted. Now the second trap is avoided, But damn - the first trap is 
-  popping up again. Eventually, after some code restructuring, the differing
-  requirements of serializating <code style="white-space: normal">construct_from</code>
-  are reconciled.
-</ol>
-Note that in this second scenario
-<ul>
-  <li>all errors are trapped at compile time.
-  <li>no invalid archives are created.
-  <li>no data is lost.
-  <li>no runtime errors occur.
-</ul>
-
-It's true that these traps may sometimes flag code that is currently correct and
-that this may be annoying to some programmers.  However, this example illustrates
-my view that these traps are useful and that any such annoyance is small price to
-pay to avoid particularly vexing programming errors.

+<h2><a name="differences_1_45"></a>Differences from Boost 1.45</h2>
+Since the release of version 1.42, it has been discovered that binary
+archives created by versions 1.42-1.44 cannot always be read by the
+recent binary archive code.  Work has proceeded in detecting the source
+of these anomolies and those which have been reported with test cases
+have been fixed.  As of this writing, it is not known whether all
+binary archives created with these versions can be loaded.
+<h2><a name="differences_1_43"></a>Differences from Boost 1.43</h2>
+<ul>
+    <li>fixed bug in the serialization of virtual base classes.  Due
+    to heroic efforts by Takatoshi Kondo.
+    <li>Native binary archives created under versions 1.42 and 1.43
+    suffer from a serious problem.  It's likely they won't be readable
+    by this latest version. This due to the fact that 1.42 made some
+    changes in the binary format of some types.  Normally this could
+    be addressed by detecting the library version number written into
+    the archive header.  Unfortunately, this library version number
+    was not incremented at 1.42 as it should have been.  So now we have
+    two different binary archive versions with the same library version
+    number.
+    <p>
+    This has been addressed by including a small utility in the example
+    directory named fix_six.cpp.  This should be run with the command line<br>
+    <code><pre>
+    fix_six &lt;file name&gt;
+    </pre></code>
+    This will assign 7 to the library version number of the archive. This
+    fix will need to ba applied to native binary archives created with
+    boost versions 1.42 and 1.43.
+</ul>
+<h2><a name="differences_1_42"></a>Differences from Boost 1.42</h2>
+<ul>
+    <li>fixed failure of shared_ptr serialization when serializing pointers
+created from enable_shared_from_this.
+    <li>added example for a simple archive which can be used as a debug log.
+This example illustrates the implemenation of the archive concept to aid
+understanding required to create one's own archive classes. The resulting
+archive is useful for debugging in that it only 160 lines of code and is
+header only - that is, it doesn't required linking to the serialization library.
+    <li>replaced example used to show how to derive from an existing archive.
+This example creates an XML archive class which doesn't include serialization
+traits such as class_id, class_version, etc.  It might be useful for exporting
+one's class information to osme XML processor and/or debugging programs.
+    <li>compile time warnings have been implemented to detect practices which
+    though correct, will result in operation or side effects different than
+    a user probably intends.

+This library has been tested against Boost version 1.39 and 1.40.
+<p>
+    Changes have been made to archive classes included with the library. Users who 
+    have used these a guide to making their own archive classes will find that 
+    these will likely no longer compile. This can be remedied by making the 
+    following changes in the code which instantiates these archive classes.

+<h3><a name="motivation">Motivation</a></h3>
+The serialization library relies on the existence of a number
+of static variables and tables to store information related
+to runtime types.  Examples are tables which relate exported
+names to types and tables which relate base classes to derived
+classes.  Construction, destruction and usage of these variables
+requires consideration of the following issues:
+<ul>
+  <li>Some static data variables and constants  entries refer to others.  
+  The sequence of initialization cannot be arbitrary but must be in proper
+  sequence.</li>
+  <li>A number of static variables aren't referred explicitly and, without
+  special precautions, will be stripped by most code optimizers</li>
+  <li>Many of these variables are created by templates and special care must
+  be taken to be sure that they are instantiated</li>
+  <li>In a multi-threading system, its possible that these static variables
+  will be accessed concurrently by separate threads.  This would create a
+  race condition with unpredictabe behavior</li>
+</ul>
+This singleton class addresses all of the above issues.
+
+<h3><a name="features">Features</a></h3>
+This singleton implementation has the following features:
+<ul>
+  <li>
+    Any instance will be constructed before any attempt is made to access it.</li>
+  <li>
+    Any instance created with a template is guarenteed to be instantiated.
+  <li>
+    Regardless of whether or not an instance has been explicitly
+    referred to, it will not be stripped by the optimizer when the
+    executable is built in release mode.
+  <li>
+    All instances are constructed before 
+    <code style="white-space: normal">main</code> is called
+    regardless of where they might be referenced within the program.
+    In a multi-tasking system, this guarentees that there will be no 
+    race conditions during the construction of any instance.  No
+    thread locking is required to guarentee this.
+  <li>
+    The above implies that any <code style="white-space: normal">const</code>
+    instances are thread-safe during the whole program.  Again, no
+    thread locking is required.
+  <li>
+    If a mutable instance is created, and such an instance is modified
+    after main is called in a mult-threading system, there exists
+    the possibility that a race condition will occur.  The serialization
+    library takes care that in the few places where a mutable
+    singleton is required, it is not altered after 
+    <code style="white-space: normal">main</code> is called.
+    For a more general purpose usage, thread locking on this
+    singleton could easily be implemented.  But as the serialization
+    library didn't require it, it wasn't implemented.
+</ul>
+

+<h3><a name="requirements">Requirements</a></h3>
+In order to be used as 
+<a target="singleton.hpp" href = "../../../boost/serialization/singleton.hpp">
+<code style="white-space: normal">
+singleton&lt;T&gt;
+</code> 
+</a>
+, the type T must be default constructable.
+It doesn't require static variables - though it may have them.
+Since the library guarentees that only one instance of 
+<a target="singleton.hpp" href = "../../../boost/serialization/singleton.hpp">
+<code style="white-space: normal">
+singleton&lt;T&gt;
+</code> 
+</a>
+and all accesss is through the above static interface
+functions, common member functions of T become
+the functional equivalent of 
+<code style="white-space: normal">static</code> functions.
+
+<h3><a name="example">Examples</a></h3>
+There are at least two different ways to use this class template.
+Both are used in the serialization library.
+<p>
+The first way is illustrated by and excerpt from the file
+<code style="white-space: normal"><a target="extended_type_info" href="../src/extended_type_info.cpp">extended_type_info.cpp</a></code>.
+which contains the following code:
+
+<pre><code>
+typedef std::set<const extended_type_info *, key_compare> ktmap;
+...
+void
+extended_type_info::key_register(const char *key) {
+    ...
+    result = singleton<ktmap>::get_mutable_instance().insert(this);
+    ...
+}
+</code></pre>
+Just by referring to the singleton instance anywhere in the program
+will guarentee that one and only one instance for the specified
+type (<code style="white-space: normal">ktmap</code> in this example) 
+will exist throughout the program.  There is no need for anyother
+declaration or definition.
+<p>
+A second way is to use 
+<a target="singleton.hpp" href = "../../../boost/serialization/singleton.hpp">
+<code style="white-space: normal">
+singleton&lt;T&gt;
+</code> 
+</a>
+as one of the base classes of the type.  This is illustrated by a simplified
+excerpt from
+<a target="extended_type_info_typeid.hpp" href = "../../../boost/serialization/extended_type_info_typeid.hpp">
+<code style="white-space: normal">
+extended_type_info_typeid.hpp
+</code> 
+</a>
+
+<pre><code>
+template&lt;class T&gt;
+class extended_type_info_typeid : 
+    public detail::extended_type_info_typeid_0,
+    public singleton&lt;extended_type_info_typeid&lt;const T&gt; &gt;
+{
+    friend class singleton&lt;extended_type_info_typeid&lt;const T&gt; &gt;;
+private:
+    // private constructor to inhibit any existence other than the 
+    // static one.  Note: not all compilers support this !!!
+    extended_type_info_typeid() :
+        detail::extended_type_info_typeid_0()
+    {
+        type_register(typeid(T));
+    }
+    ~extended_type_info_typeid(){}
+    ...
+};
+</code></pre>
+
+This usage will permit a more natural syntax to be used:
+<pre><code>
+extended_type_info_typeid&lt;T&gt;::get_const_instance()
+</code></pre>
+
+Again, including one or more of the above statements anywhere
+in the program will guarentee that one and only one instance
+is created and referred to.
+
+<h3><a name="multithreading">Multi-Threading</a></h3>
+This singleton CAN be safely used in multi-threading applications if one
+is careful follow a simple rule:
+<p>
+<b>Do not call get_mutable_instance when more than one thread is running!</b>
+<'>
+All singletons used in the serialization library follow this rule.  
+In order to help detect accidental violations of this rule there
+exists an singleton lock/unlock functions.
+<pre><code>
+void boost::serialization::singleton_module::lock();
+void boost::serialization::singleton_module::unlock();
+bool boost::serialization::singleton_module::is_locked();
+</code></pre>
+In a program compiled for debug, any invocation of 
+<code style="white-space: normal">get_mutable_instance()</code>
+while the library is in a "locked" state will trap in an assertion.
+The singleton module lock state is initialized as "unlocked" to permit
+alteration of static variables before 
+<code style="white-space: normal">main</code> is called. 
+The <code style="white-space: normal">lock()</code> and
+<code style="white-space: normal">unlock()</code> are "global"
+in they affect ALL the singletons defined by this template.
+All serialization tests invoke <code style="white-space: normal">lock()</code>
+at the start of the progam.  For programs compiled in release
+mode these functions have no effect.

+<a target="detail" href="traits.html#export">Elsewhere</a> in this manual, we have described 
+<code style="white-space: normal">BOOST_CLASS_EXPORT</code>. 
+Export implies two things:
+<ul>
+<li>Instantiates code which is not otherwise referred to.
+<li>Associates an external identifier with the class to be serialized.
+The fact that the class isn't explicitly referred to implies this
+requirement.
+</ul>
+In C++, usage of code not explicitly referred to is implemented via
+virtual functions.  Hence, the need for export is implied by the 
+usage of a derived class that is manipulated via a pointer or
+reference to it's base class.
+
+<p>
+<code style="white-space: normal">BOOST_CLASS_EXPORT</code> in the same
+source module that includes any of the archive class headers will
+instantiate code required to serialize polymorphic pointers of
+the indicated type to the all those archive classes. If no
+archive class headers are included, then no code will be instantiated.
+
+<p>
+Note that the implemenation of this functionality requires
+that the <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+macro appear <b>after</b> and the inclusion of any archive
+class headers for which code is to be instantiated.
+So, code that uses <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+will look like the following:
+<pre><code>
+#include &lt;boost/archive/text_oarchive.hpp&gt;
+#include &lt;boost/archive/text_oarchive.hpp&gt;
+... // other archives
+
+#include "a.hpp" // header declaration for class a
+BOOST_CLASS_EXPORT(a)
+... // other class headers and exports
+</code></pre>
+This will be true regardless of whether the is part
+of a stand alone executable, a static library or
+a dyanmic or shared library.  
+<p>
+Including
+<code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+in the "a.hpp" header itself as one would do with
+other serialization traits will make it difficult
+or impossible to follow the rule above regarding
+inclusion of archive headers before
+<code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+is invoked. This can best be addressed by using
+<code style="white-space: normal">BOOST_CLASS_EXPORT_KEY</code>
+in the header declarations and
+<code style="white-space: normal">BOOST_CLASS_EXPORT_IMPLEMENT</code>
+in the class definition file.
+
+<p>
+This system has certain implications for placing code in static or shared
+libraries.  Placing <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+in library code will have no effect unless archive class headers are
+also included.  So when building a library, one should include all headers
+for all the archive classes which he anticipates using. Alternatively,
+one can include headers for just the
+<a href="archive_reference.html#polymorphic">Polymoprhic Archives</a>.
+
+<p>
+Strictly speaking, export should not be necessary if all pointer serialization
+occurs through the most derived class.  However, in order to detect
+what would be catastophic error, the library traps ALL serializations through
+a pointer to a polymorphic which are not exported or otherwise registered.
+So, in practice, be prepared to register or export all classes with one
+or more virtual functions which are serialized through a pointer. 
+

+Note that the implementation of this functionality depends upon vendor
+specific extensions to the C++ language.  So, there is no guarenteed portability
+of programs which use this facility.  However, all C++ compilers which

+<h3><a name="static_libraries">Static Libraries and Serialization</a></h3>
+Code for serialization of data types can be saved in libraries
+just as it can for the rest of the type implementation.
+This works well, and can save huge amount of compilation time.
+<ul>
+<li>Only compile serialization definitions in the library.
+<li>Explicitly instantiate serialization code for ALL
+archive classes you intend to use in the library.
+<li>For exported types, only use <code style="white-space: normal">BOOST_CLASS_EXPORT_KEY</code>
+in headers.
+<li>For exported types, only use <code style="white-space: normal">BOOST_CLASS_EXPORT_IMPLEMENT</code>
+in definitions compiled in the library.  For any particular type,
+there should be only one file which contains
+<code style="white-space: normal">BOOST_CLASS_EXPORT_IMPLEMENT</code>
+for that type.  This ensures that only one copy
+of serialization code will exist within the program.  It avoids
+wasted space and the possibility of having different

+Including
+<code style="white-space: normal">BOOST_CLASS_EXPORT_IMPLEMENT</code>

+<h3><a name="dlls">DLLS - Serialization and Runtime Linking</a></h3>
+Serialization code can be placed in libraries to be linked at runtime.  That is,
+code can be placed in DLLS(Windows) Shared Libraries(*nix), or static libraries
+as well as the main executable.  The best technique is the
+same as that described above for libraries.  The serialization
+library test suite includes the following programs
+to illustrate how this works:
+<p>
+
+<a href = "../test/test_dll_simple.cpp" target="test_dll_simple">
+<code style="white-space: normal">test_dll_simple</code>
+</a>,
+and
+<a href = "../test/dll_a.cpp" target="dll_a">
+<code style="white-space: normal">dll_a.cpp</code>
+</a>
+where implementation of serializaton is also completely separate
+from the main program but the code is loaded at runtime.  In this
+example, this code is loaded automatically when the program which
+uses it starts up, but it could just as well be loaded and unloaded 
+with an OS dependent API call.
+<p>
+Also included are
+<a href = "../test/test_dll_exported.cpp" target="test_dll_exported">
+<code style="white-space: normal">test_dll_exported.cpp</code>
+</a>,
+and
+<a href = "../test/polymorphic_derived2.cpp" target="polymorphic_derived2">
+<code style="white-space: normal">polymorphic_derived2.cpp</code>
+</a>
+which are similar to the above but include tests of the export
+and no_rtti facilities in the context of DLLS.
+<p>
+For best results, write your code to conform to the following
+guidelines:
+<ul>
+  <li>Don't include <code>inline</code> code in classes used in DLLS.
+This will generate duplicate code in the DLLS and mainline. This
+needlessly duplicates code.  Worse, it makes is possible for 
+different versions of the same code exist simultaneously.  This
+type of error turns out to be excruciatingly difficult to debug.
+Finally, it opens the possibility that module being referred to
+might be explictly unloaded which would (hopefully) result in
+a runtime error. This is another bug that is not always 
+reproducible or easy to find. For class member templates use something like
+
+<pre><code>
+template&lt;class Archive&gt;
+void serialize(Archive & ar, const unsigned int version);
+</code></pre>
+in the header, and
+
+<pre><code>
+template&lt;class Archive&gt;
+void myclass::serialize(Archive & ar, const unsigned int version){
+	...
+}
+
+BOOST_EXPORT_CLASS_IMPLEMENT(my_class)
+
+#include &lt;boost/archive/text_oarchive&gt;
+#include &lt;boost/archive/text_iarchive&lt;
+template myclass::serialize(boost::archive::text_oarchive & ar, const unsigned int version);
+template myclass::serialize(boost::archive::text_iarchive & ar, const unsigned int version);
+... // repeat for each archive class to be used.
+</code></pre>
+in the implementation file.  This will result in generation of all code
+required in only one place.  The library does not detect this type of error for you.
+  <li>If DLLS are to be loaded an unloaded explicitly (e.g. using <code>dlopen</code> in *nix or 
+<code>LoadLibrary</code> in Windows).  Try to arrange that they are unloaded in the reverse
+sequence.  This should guarentee that problems are avoided even if the
+above guidline hasn't been followed.
+
+</ul>
+
+<h3><a name="plugins">Plugins</a></h3>
+In order to implement the library, various facilities for runtime
+manipulation of types are runtime were required.  These
+are <a target="detail" href="extended_type_info.html"><code>extended_type_info</code></a>
+for associating classes with external identifying strings (<b>GUID</b>)
+and <a target="detail" href="void_cast.html"><code>void_cast</code></a>
+for casting between pointers of related types.
+
+To complete the functionality of 
+<a target="detail" href="extended_type_info.html"><code>extended_type_info</code></a>
+the ability to construct and destroy corresponding types has been
+added.  In order to use this functionality, one must specify
+how each type is created.  This should be done at the time
+a class is exported.  So, a more complete example of the code above would be:
+
+<pre><code>
+#include &lt;boost/archive/text_oarchive.hpp&gt;
+#include &lt;boost/archive/text_oarchive.hpp&gt;
+... // other archives
+
+#include "a.hpp" // header declaration for class a
+
+// this class has a default constructor
+BOOST_SERIALIZATION_FACTORY_0(a)
+// as well as one that takes one integer argument
+BOOST_SERIALIZATION_FACTORY_1(a, int)
+
+// specify the GUID for this class
+BOOST_CLASS_EXPORT(a)
+... // other class headers and exports
+</code></pre>
+
+With this in place, one can construct, serialize and destroy
+about which only is know the <b>GUID</b> and a base class.
+

-in having multiple open archives from one or more threads.
+The fundamental purpose of serialization would conflict with multiple

+The library implementation presumes that the application avoids such an situtation.
 <p>
-Well, not quite.
+However, Writing/Reading different archives simultaneously

+completely independent from any other archive instance.  The only shared

 <p>
-There are a couple of global data structures for holding
-information of serializable types.  These structures are
-used to dispatch to correct code to handle each pair
-of serializable types and archive types.  Since this
-information is shared among all archives, there is 
-potential for problems.  This has been addressed
-carefully implementing the library so that these 
-structures are all initialized before 
-<code style="white-space: normal">main(...)</code>
-is called.  From then on they are never altered.  So
-there SHOULD be no problem having mulitple archives
-open simultaneously - be it from the same or different
-threads.
-<p>
-Well, almost.
-<p>
-With dynamically loaded code - DLLS or Shared Libraries, 
-these global data structures can be altered when a library
-is loaded or unloaded.  That is, in this case, these
-globa data structures can be altered after 
-<code style="white-space: normal">main(...)</code>
-is called.  So if a thread is dynamically loading/unloading
-modules which contain serialization code while an 
-archive is open there could be problems.  Also, if
-such loading/unloading is happening concurrently
-in different threads, there could also be problems.
-<p>
-It might not be easy to control this.  Is possible that
-some systems may not actually load modules until they
-are actually needed.  So even though we think that
-there is not dynamic loading/unloading of such code
-it could be occurring as "help" to manage resources.
-On such systems, access to archive code would have 
-to be syncronized with some multi-threading construct
-in order to be functional.
+This singleton implementation guarentees that all of this shared
+information is initialized when the code module which contains
+them is loaded.  The serialization library takes care to
+ensure that these data structures are not subsequently
+modified. The only time there could be a problem would
+be if code is loaded/unloaded while another task is
+serializing data.  This could only occur for types whose 
+serialization is implemented in a dynamically loaded/unload DLL
+or shared library.  So if the following is avoided:
+<ul>
+    <li>Accessing the same archive instance from different tasks.
+    <li>Loading/Unloading DLLS or shared libraries while any archive
+    instances are open.
+</ul>
+The library should be thread safe.

+These are enhancements that the serialization library needs but have not been done.
+Some of these projects, though tricky, are not huge and would be suitable
+for someone who has a limited time to spend on them.  In particular, they
+might be of interest as student projects such as the Google Summer of Code.
+
+<h2><a name="portablebinaryarchives"></a>Portable Binary Archives</h2>
+Currently there is a portable binary archive in the examples directory.
+It is not regularly submitted to the exhaustive boost testing regimen
+but it is tested occasionally and has been used in production code.
+<p>
+Its missing the following:
+<ul>
+  <li>Addition of portable floating point types.  This is not trivial.  In addition to
+  handling floating point types of varying sizes, It requires
+  handling invalid floating point numbers (NaNs) in a portable manner.
+  <li>Some way to test archive portability within the Boost testing regimen.
+  <li>Integration into the Boost testing similar to the other archive classes.
+</ul>
+
+<h2><a name="performancetesting"></a>Performance Testing and Profiling</h2>
+
+I've managed to setup performance profiling using the following:
+<ul>
+  <li>current (as I write this) Boost.Build tools.
+  <li>the gcc compiler.
+  <li>and a shell script - profile.sh
+  <li>library_status program from the tools/regression/src directory
+</ul>
+Invoking profile script produces a 
+<a href="performance_status.html">table</a>
+which shows the results of each test and links to the actual
+profile.
+<p>
+The first thing I did was include some of the serialization library tests.
+It became immediatly apparent that these tests were totally unsuitable
+for performance testing and that new tests needed to be written for this 
+purpose.  These tests would highlight the location of any performance
+bottlenecks in the serialization library.  Whenever I've subjected my
+code in the past to this type of analysis, I've always been suprised
+to find bottlenecks in totally unanticipated places and fixing those
+has always lead to large improvements in performance.  I expect that
+this project would have a huge impact on the utility of the serialization
+library.
+
+<h2><a name="backversioning"></a>Back Versioning</h2>
+
+It has been suggested that a useful feature of the library would be
+the ability to create "older versions" of archives.  Currently,
+the library permits one make programs that are guarenteed
+the ability to load archives with classes of a previous version. 
+But there is not way to save classes in accordance with a
+previous version.  At first I dismissed this a a huge project
+with small demand.  A cursory examination of the code revealed
+that this would not be very difficult.  It would require some
+small changes in code and some additional tests.  Also it
+would require special treatment in the documentation - perhaps
+a case study.
+
+
+<h2><a name="nortti"></a>Environments without RTTI</h2>
+
+I note that some have commented that this library requires RTTI.
+This is not strictly true.  The examples and almost all the
+tests presume the existence of RTTI.  But it should be possible
+to use the library without it.  The example used for testing is an 
+<code style="white-space: normal">extended_typeinfo</code> 
+implemenation which presumes that all classes names have been exported. 
+So, to make this library compatible for platforms without RTTI, 
+a set of tests, examples and new manual section would have to be created

+<code style="white-space: normal"><pre>
+T * t;
+ar >> t;
+</pre></code>
+
+if the tracking_level serialization trait is set to "track_never".
+<p>
+
+The following case illustrates the function of this message.
+It was originally used as an example in the
+mailing list by Peter Dimov.
+
+<code style="white-space: normal"><pre>
+class construct_from 
+{ 
+    ... 
+}; 
+
+void main(){ 
+    ... 
+    Y y; 
+    construct_from x(y); 
+    ar &lt;&lt; x; 
+} 
+</pre></code>
+
+Suppose that the above message is not displayed and the code is used as is.
+<ol>
+  <li>this example compiles and executes fine. No tracking is done because 
+  construct_from has never been serialized through a pointer. Now some time 
+  later, the next programmer(2) comes along and makes an enhancement. He 
+  wants the archive to be sort of a log. 
+
+<code style="white-space: normal"><pre>
+void main(){ 
+    ... 
+    Y y; 
+    construct_from x(y); 
+    ar &lt;&lt; x; 
+    ... 
+    x.f(); // change x in some way 
+   ... 
+    ar &lt;&lt; x 
+} 
+</pre></code>
+  <p>
+  Again no problem. He gets two different of copies in the archive, each one is different. 
+  That is he gets exactly what he expects and is naturally delighted. 
+  <p>
+  <li>Now sometime later, a third programmer(3) sees construct_from and says - 
+  oh cool, just what I need. He writes a function in a totally disjoint 
+  module. (The project is so big, he doesn't even realize the existence of 
+  the original usage) and writes something like: 
+
+<code style="white-space: normal"><pre>
+class K { 
+    shared_ptr &lt;construct_from&gt; z; 
+    template &lt;class Archive&gt; 
+    void serialize(Archive & ar, const unsigned version){ 
+        ar &lt;&lt; z; 
+    } 
+}; 
+</pre></code>
+
+  <p>
+  He builds and runs the program and tests his new functionality. It works 
+  great and he's delighted. 
+  <p>
+  <li>Things continue smoothly as before.  A month goes by and it's 
+  discovered that when loading the archives made in the last month (reading the 
+  log). Things don't work. The second log entry is always the same as the 
+  first. After a series of very long and increasingly acrimonius email exchanges, 
+its discovered 
+  that programmer (3) accidently broke programmer(2)'s code .This is because by 
+  serializing via a pointer, the "log" object now being tracked.  This is because
+  the default tracking behavior is "track_selectively".  This means that class
+  instances are tracked only if they are serialized through pointers anywhere in
+  the program. Now multiple saves from the same address result in only the first one 
+  being written to the archive. Subsequent saves only add the address - even though the 
+  data might have been changed.  When it comes time to load the data, all instances of the log record show the same data.
+  In this way, the behavior of a functioning piece of code is changed due the side
+  effect of a change in an otherwise disjoint module.
+  Worse yet, the data has been lost and cannot not be now recovered from the archives.
+  People are really upset and disappointed with boost (at least the serialization system).
+  <p>
+  <li>
+  After a lot of investigation, it's discovered what the source of the problem
+  and class construct_from is marked "track_never" by including:
+<code style="white-space: normal"><pre>
+BOOST_CLASS_TRACKING(construct_from, track_never) 
+</pre></code>
+  <li>Now everything works again. Or - so it seems.
+  <p>
+  <li><code style="white-space: normal">shared_ptr&lt;construct_from&gt;</code>
+is not going to have a single raw pointer shared amongst the instances. Each loaded 
+<code style="white-space: normal">shared_ptr&lt;construct_from&gt;</code> is going to 
+have its own distinct raw pointer. This will break 
+<code style="white-space: normal">shared_ptr</code> and cause a memory leak.  Again,
+The cause of this problem is very far removed from the point of discovery.  It could 
+well be that the problem is not even discovered until after the archives are loaded.
+Now we not only have difficult to find and fix program bug, but we have a bunch of
+invalid archives and lost data.
+</ol>
+
+<p>Now consider what happens when the message is displayed:
+
+<ol>
+  <p>
+  <li>Right away, the program traps at 
+<code style="white-space: normal"><pre>
+ar &lt;&lt; x; 
+</pre></code>
+  <p>
+  <li>The programmer curses (another %^&*&* hoop to jump through). If he's in a 
+  hurry (and who isn't) and would prefer not to <code style="white-space: normal">const_cast</code>
+  - because it looks bad.  So he'll just make the following change an move on. 
+<code style="white-space: normal"><pre>
+Y y; 
+const construct_from x(y); 
+ar &lt;&lt; x; 
+</pre></code>
+  <p>
+  Things work fine and he moves on. 
+  <p>
+  <li>Now programer (2) wants to make his change - and again another 
+  annoying const issue; 
+<code style="white-space: normal"><pre>
+Y y; 
+const construct_from x(y); 
+... 
+x.f(); // change x in some way ; compile error f() is not const 
+... 
+ar &lt;&lt; x 
+</pre></code>
+  <p>
+  He's mildly annoyed now he tries the following: 
+  <ul>
+    <li>He considers making f() a const - but presumable that shifts the const 
+    error to somewhere else. And his doesn't want to fiddle with "his" code to 
+    work around a quirk in the serializaition system 
+    <p>
+    <li>He removes the <code style="white-space: normal">const</code>
+    from <code style="white-space: normal">const construct_from</code> above - damn now he 
+    gets the trap. If he looks at the comment code where the 
+    <code style="white-space: normal">BOOST_STATIC_ASSERT</code>
+    occurs, he'll do one of two things 
+    <ol>
+      <p>
+      <li>This is just crazy. Its making my life needlessly difficult and flagging 
+      code that is just fine. So I'll fix this with a <code style="white-space: normal">const_cast</code>
+      and fire off a complaint to the list and mabe they will fix it. 
+      In this case, the story branches off to the previous scenario.
+      <p>
+      <li>Oh, this trap is suggesting that the default serialization isn't really 
+      what I want. Of course in this particular program it doesn't matter. But 
+      then the code in the trap can't really evaluate code in other modules (which 
+      might not even be written yet). OK, I'll add the following to my 
+      construct_from.hpp to solve the problem. 
+<code style="white-space: normal"><pre>
+BOOST_CLASS_TRACKING(construct_from, track_never) 
+</pre></code>
+    </ol>
+  </ul>
+  <p>
+  <li>Now programmer (3) comes along and make his change. The behavior of the 
+  original (and distant module) remains unchanged because the 
+  <code style="white-space: normal">construct_from</code> trait has been set to 
+  "track_never" so he should always get copies and the log should be what we expect.
+  <p>
+  <li>But now he gets another trap - trying to save an object of a 
+  class marked "track_never" through a pointer. So he goes back to 
+  construct_from.hpp and comments out the 
+  <code style="white-space: normal">BOOST_CLASS_TRACKING</code> that 
+  was inserted. Now the second trap is avoided, But damn - the first trap is 
+  popping up again. Eventually, after some code restructuring, the differing
+  requirements of serializating <code style="white-space: normal">construct_from</code>
+  are reconciled.
+</ol>
+Note that in this second scenario
+<ul>
+  <li>all errors are trapped at compile time.
+  <li>no invalid archives are created.
+  <li>no data is lost.
+  <li>no runtime errors occur.
+</ul>
+
+It's true that these messages may sometimes flag code that is currently correct and
+that this may be annoying to some programmers.  However, this example illustrates
+my view that these messages are useful and that any such annoyance is small price to
+pay to avoid particularly vexing programming errors.
+
+</dd>
+
+<dt><h2><a name="pointer_level">pointer_level</a> - warning</h2></dt>
+<dd>
+This trap addresses the following situaion when serializing 
+a pointer:
+<ul>
+<li>A type doesn't save class information in the
+archive. That is, the serialization trait implementation
+level <= object_serializable.
+<li>Tracking for this type is set to "track selectively"
+in this case, indication that an object is tracked is
+not stored in the archive itself - see level == object_serializable.
+Since class information is not saved in the archive, the existence
+or absense of the operation ar << T * anywhere else in the 
+program is used to infer that an object of this type should be tracked.
+<p>
+A problem arises when a program which reads an archive
+includes the operation ar >> T * so that tracking information
+will be included in the archive. When a program which
+creates the archive doesn't include ar << T it is presumed
+that the archive doesn't include tracking information and
+the archive will fail to load.  Also the reverse situation could 
+trigger a similar problem.
+<p>
+Though this situation is unlikely for several reasones, 
+it is possible - hence this warning. 
+</ul>
+So if your program traps here, consider changing the 
+tracking or implementation level traits - or not
+serializing via a pointer.
+</dd>
+
+<dt><h2><a name="pointer_tracking">pointer_tracking</a> - warning</h2></dt>
+<dd>
+Serializing an object of a type marked "track_never" through a pointer
+could result in creating more objects than were saved! There are cases
+in which a user might really want to do this so we leave it as a warning.
+</dd>
+
+<dt><h2><a name="const_loading">const_loading</a> - error</h2></dt>
+<dd>
+One cannot load data into a "const" object unless it's a
+wrapper around some other non-const object.
