+These are not part of the library itself, but rather

+
+<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.

+ This table describes the call tree of the program, and was sorted by

+		Index numbers are sorted numerically.
+		The index number is printed next to every function name so

+
+     % 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

+		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.

+		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:

+<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>
+<p>
+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>
+boost::serialization::global_lock::get_mutable_instance().lock();
+boost::serialization::global_lock::get_mutable_instance().unlock();
+</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 global_lock state is initialized as "unlocked" to permit
+alteration of static variables before 
+<code style="white-space: normal">main</code> is called. 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.

-that code should be instantiated for serialization of a given class even though the

-<p>
-There are several ways <code style="white-space: normal">BOOST_CLASS_EXPORT</code> could have been
-implemented.
-<p>
-One approach would be to instantiate serialization code  for all archive classes included in the library.
-This would add to each executable a large amount of code that is most likely never called.
-Also it would needlessly slow down compilations of any program that uses the library.  Finally,
-the list of archives would be "built-in" to the library which would compilicate the addition of
-new or custom archive classes.
-<p>
-Another approach would be for the library user to somehow explicitly instantiate which archive classes 
-code should be instantiated for each class to be serialized. Users would have to include
-header files corresponding the archive classes to be instantiated.
-The list of instantiated archive classes would have to be manually kept in sync with the
-archive class headers actually included.  This was considered burdensome and error prone.
-<p>
-This implementation of <code style="white-space: normal">BOOST_CLASS_EXPORT</code> works in the 
-following way:
-<ul>
-  <li>All header modules of the form &lt;boost/archive/*archive.hpp&gt; are required to precede 
-  the header module <a href="../../../boost/serialization/export.hpp" target="export_hpp">export.hpp</a>.
-  <li>The header <a href="../../../boost/serialization/export.hpp" target="export_hpp">export.hpp</a>
-  builds a list of archive classes whose header modules have been previously included.  
-  It does this by checking to see which inclusion guard constants have been defined.
-  The header <a href="../../../boost/archive/detail/known_archive_types.hpp" target="known_archive_types_hpp">known_archive_types.hpp</a>
-  lists the archive header files which whose include guards will be checked.  If you create your own
-  archive class, you probably want to edit this file.
-  <li><code style="white-space: normal">BOOST_CLASS_EXPORT(my_class)</code> explicitly instantiates
-  serialization code for <code style="white-space: normal">my_class</code> for each archive in the list.
-</ul>
-Serialization code will be instantiated for a given archive class 
-if and only if the module that defines that archive class has been included in the program. 
-Given this, our program will contain all necessary code instantiations and no other.
-<p>
-For many styles of code organization this header sequencing requirement presents little problem. 
- 
-Serialization code organized by class headers that are designed to be independent of archive
-implementations will look something like the following:
-<code><pre>
-// A.hpp
-// Note:to preserve independence from any particular archive implementation,
-// no headers from &lt;boost/archive/...&gt; are included.
-// Headers can be included in any order.
-#include &lt;boost/serialization/...&gt;
-#include &lt;boost/serialization/export.hpp&gt;
-... // include other headers that A depends upon
-
-class A {
-	...
-};
-
-BOOST_CLASS_EXPORT(A) // note: the export name of this class
-</pre></code>
-This style:
-<ul>
-  <li>permits the header to include all aspects of the serialization implementation.
-  <li>permits the header to be included anywhere else as part of some other class declaration.
-  <li>reflects the concept of headers as a "library of types" which
-  can be used independently in other programs or other parts of the same program.
-  <li>reflects a fundamental principle of the serialization library design in that the 
-  specification of serialization of any class is independent of any archive implementation.
-</ul>
-However, it might not always be possible or convenient to conform to the above style. Something
-like the following might be required or preferred:
-<code><pre>
-// A.hpp
-// headers can be included in any order
-#include &lt;boost/archive/text_oarchive.hpp&gt;
-#include &lt;boost/archive/text_iarchive.hpp&gt;
-...
-#include &lt;boost/serialization/...&gt;
-...
-// can't do the following because then A.hpp couldn't be included somewhere else
-// #include &lt;boost/serialization/export.hpp&gt;
-
-class A {
-	...
-};
-// can't do the following because export.hpp is not included !!
-//BOOST_CLASS_EXPORT(A) // note: the export name of this class
-</pre></code>
-As noted in the comments, this would work.  But 
-<code style="white-space: normal">#include &lt;.../export.hpp&gt;</code> can't be used
-without conflicting with other modules which use 
-<code style="white-space: normal">#include &lt;.../*archive.hpp&gt;</code>.  In this
-case we can move the export to an implementation file:
-<code><pre>
-// A.cpp

+<h3><a name="export">Exporting Class Serialization</a></h3>
+<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>
+Note that 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 is different than other serialization
+traits which would normally be included in same file
+as the class declaration.
+
+<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>.
+Also, when making shared libraries, there is currently a restriction
+that only one such library can use <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+for any given type. All this will most likely make it inconvenient
+to include <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+as part of the header of the class to be serialized. So, <b>the 
+best way to use <code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+is to include it in the same module which implements the class</b>.
+
+<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. 
+
+<p>
+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
+are tested with boost provide the required extensions.  The library
+includes the extra declarations required by each of these compilers.
+It's reasonable to expect that future C++ compilers will support
+these extensions or something equivalent.
+
+<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.  As long as
+
+<a target="detail" href="serialization.html#export">
+<code style="white-space: normal">BOOST_CLASS_EXPORT</code>
+</a>
+
+is not used, The serialization library imposes no special requirements
+that need be taken into account when distributing code among various modules.
+<p>
+For static libraries, this is illustrated by
+<a href = "../example/demo_pimpl.cpp" target="demo_pimpl">
+<code style="white-space: normal">demo_pimpl.cpp</code>
+</a>,
+<a href = "../example/demo_pimpl_A.cpp" target="demo_pimpl">
+<code style="white-space: normal">demo_pimpl_A.cpp</code>
+</a>
+and
+<a href = "../example/demo_pimpl_A.hpp" target="demo_pimpl">
+<code style="white-space: normal">demo_pimpl_A.hpp</code>
+</a>
+where implementation of serializaton is in a static library 
+completely separate from the main program.
+
+<p>
+For runtime linked libraries this is illustrated by one of the tests:
+
+<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.
+
+<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.
+
+
+<h3><a name="multi_threading">Multi-Threading</a></h3>
+The fundamental purpose of serialization would conflict with multiple 
+thread concurrently writing/reading from/to a single open archive instance.
+The library implementation presumes that the application avoids such an situtation.
+<p>
+However, Writing/Reading different archives simultaneously
+in different tasks is permitted as each archive instance is (almost) 
+completely independent from any other archive instance.  The only shared 
+information are some type tables which have been implemented using a 
+lock-free thread-safe 
+<a target="detail" href="singleton.html">
+<code style="white-space: normal">singleton</code>
+</a>
+described elsewhere in this documentation.
+<p>
+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.

+<h3><a name="optimizations">Optimizations</a></h3>
+In performance critical applications that serialize large sets of contiguous data of homogeneous
+types one wants to avoid the overhead of serializing each element individually, which is
+the motivation for the <a href="wrappers.html#arrays"><code>array</code></a>
+wrapper.
+
+Serialization functions for data types containing contiguous arrays of homogeneous
+types, such as for <code>std::vector</code>, <code>std::valarray</code> or  
+<code>boost::multiarray</code> should serialize them using an
+<a href="wrappers.html#arrays"><code>array</code></a> wrapper to make use of 
+these optimizations.
+
+Archive types that can provide optimized serialization for contiguous arrays of 
+homogeneous types should implement these by overloading the serialization of
+the  <a href="wrappers.html#arrays"><code>array</code></a> wrapper, as is done
+for the binary archives.

+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
