+    \title XML Stream Lint Example
+    \ingroup xml-examples
+    \brief A commandline tool reading from an input file and writing to
+    the standard output file.
+
+    The XML Stream Lint example provides a simple command line utility that
+    accepts a file name as its single argument and writes it to the standard
+    output file.
+
+    The specified file is parsed using an QXmlStreamReader object and written
+    to the standard output file using an QXmlStreamWriter object. If the file
+    does not contain a well-formed XML document or the use of namespaces in
+    the document is incorrect, a description of the error is printed to
+    the standard error file and will appear in the console.
+
+    \section1 Basic Operation
+
+    The main function of the example opens the file specified by the user
+    for input (\c inputFile), and it uses QFile to access the standard output
+    file.
+
+    Reading XML is handled by an instance of the QXmlStreamReader class, which
+    operates on the input file object; writing is handled by an instance of
+    QXmlStreamWriter operating on the output file object:
+
+    \snippet xmlstreamlint/main.cpp 0
+
+    The work of parsing and rewriting the XML is done in a while loop, and is
+    driven by input from the reader:
+
+    \snippet xmlstreamlint/main.cpp 1
+
+    If more input is available, the next token from the input file is read
+    and parsed. If an error occurred, information is written to the standard
+    error file via a stream, and the example exits by returning a non-zero
+    value from the main function.
+
+    \snippet xmlstreamlint/main.cpp 2
+
+    For valid input, the writer is fed the current token from the reader,
+    and this is written to the output file that was specified when it was
+    constructed.
+
+    When there is no more input, the loop terminates, and the example can
+    exit successfully.
