+\section _intro Introduction
+
+<a HREF="http://www.json.org/">JSON (JavaScript Object Notation)</a>
+ is a lightweight data-interchange format.
+It can represents integer, real number, string, an ordered sequence of value, and
+a collection of name/value pairs.
+
+Here is an example of JSON data:
+\verbatim
+// Configuration options
+{
+ // Default encoding for text
+ "encoding" : "UTF-8",
+
+ // Plug-ins loaded at start-up
+ "plug-ins" : [
+ "python",
+ "c++",
+ "ruby"
+ ],
+
+ // Tab indent size
+ indent : { length : 3, use_space = true }
+}
+\endverbatim
+

+- read and write JSON document
+- rewrite JSON document preserving original comments
+
+\code
+Json::Value root; // will contains the root value after parsing.
+Json::Reader reader;
+bool parsingSuccessful = reader.parse( config_doc, root );
+if ( !parsingSuccessful )
+{
+ // report to the user the failure and their locations in the document.
+ std::cout << "Failed to parse configuration\n"
+ << reader.getFormatedErrorMessages();
+ return;
+}
+
+// Get the value of the member of root named 'encoding', return 'UTF-8' if there is no
+// such member.
+std::string encoding = root.get("encoding", "UTF-8" ).asString();
+// Get the value of the member of root named 'encoding', return a 'null' value if
+// there is no such member.
+const Json::Value plugins = root["plug-ins"];
+for ( int index = 0; index < plugins.size(); ++index ) // Iterates over the sequence elements.
+ loadPlugIn( plugins[index].asString() );
+
+setIndentLength( root["indent"].get("length", 3).asInt() );
+setIndentUseSpace( root["indent"].get("use_space", true).asBool() );
+
+// ...
+// At application shutdown to make the new configuration document:
+// Since Json::Value has implicit constructor for all value types, it is not
+// necessary to explicitely construct the Json::Value object:
+root["encoding"] = getCurrentEncoding();
+root["indent"]["length"] = getCurrentIndentLength();
+root["indent"]["use_space"] = getCurrentIndentUseSpace();
+
+Json::StyledWriter writer;
+// Make a new JSON document for the configuration. Preserve original comments.
+std::string outputConfig = writer.write( root );
