-
-    Boost library (http://boost.org) offers a serialization framework,
-    which is able to serialize even complex class structures, you only
-    need to overwrite one or two serialization macros. The
-    disadvantages are that a lot of macros are needed and it becomes
-    quite complex as soon as you need inheritance. Also the generated
-    XML is not very enhanced, especially for Lists and
-    optional. Editing the boost serialization code by hand is a pain.
-
-    Classes could also be serialized using gSOAP (http://gsoap.sf.net)
-    which is designed for the SOA-Protocol. This serialization is much
-    more flexible, but it requires a pseudo C++ declaration and a C++
-    parser/generator. Also it has very bad memory management, since it
-    is plain C internally.
-
-    Our requirements are:
-      - No precompiler, plain C++.
-      - Automatic memory management.
-      - Nice looking XML code that is easy to edit manually.
-      - Good error messages (exception) in case of bad XML files.
-      - As few ugly overflow as possible.
