+This example shows how to save/load the object model to/from XDR
+(eXternal Data Representation) binary format using XDR streams.
+The XDR API is available on most UNIX and GNU/Linux systems as part
+of Sun RPC (libtirpc-dev package on Debian/Ubuntu, libtirpc-devel
+package on Fedora/RHEL, and as a part of the Standard C Library on
+FreeBSD and MacOS). On Windows you may need to install a third-party
+library which provides the XDR API.
+
+The example consists of the following files:
+
+library.xsd
+  XML Schema which describes a library of books.
+
+library.xml
+  Sample XML instance document.
+
+library.hxx
+library.cxx
+  C++ types that represent the given vocabulary as well as data
+  representation stream insertion and extraction operations. These
+  are generated by XSD from library.xsd. Note that the
+  --generate-insertion and --generate-extraction options are used
+  to generate the insertion and extraction operations for XDR
+  stream.
+
+driver.cxx
+  Driver for the example. It first calls one of the parsing functions
+  that constructs the object model from the input XML file. It then
+  saves the object model to the XDR representation and loads it back.
+  Additionally, it prints the content of the object model before saving
+  it to the XDR representation and after loading it from the XDR
+  representation.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver library.xml
