+
+    \brief The QUrl class provides a URL parser and simplifies working with URLs.
+\if defined(commercial)
+    It is part of the <a href="commercialeditions.html">Qt Enterprise Edition</a>.

+    \module network
+
+    The QUrl class is provided for simple work with URLs. It can
+    parse, decode, encode, etc.
+
+    QUrl works with the decoded path and encoded query in turn.
+
+    Example:
+
+    <tt>http://www.trolltech.com:80/cgi-bin/test%20me.pl?cmd=Hello%20you</tt>
+
+    \table
+    \header \i Function	    \i Returns
+    \row \i \l protocol()   \i "http"
+    \row \i \l host()	    \i "www.trolltech.com"
+    \row \i \l port()	    \i 80
+    \row \i \l path()	    \i "/cgi-bin/test&nbsp;me.pl"
+    \row \i \l fileName()   \i "test&nbsp;me.pl"
+    \row \i \l query()	    \i "cmd=Hello%20you"
+    \endtable
+
+    Example:
+
+    <tt>http://doc.trolltech.com/qdockarea.html#lines</tt>
+
+    \table
+    \header \i Function	    \i Returns
+    \row \i \l protocol()   \i "http"
+    \row \i \l host()	    \i "doc.trolltech.com"
+    \row \i \l fileName()   \i "qdockarea.html"
+    \row \i \l ref()	    \i "lines"
+    \endtable
+
+    The individual parts of a URL can be set with setProtocol(),
+    setHost(), setPort(), setPath(), setFileName(), setRef() and
+    setQuery(). A URL could contain, for example, an ftp address which
+    requires a user name and password; these can be set with setUser()
+    and setPassword().
+
+    Because path is always encoded internally you must not use "%00"
+    in the path, although this is okay (but not recommended) for the
+    query.
+
+    QUrl is normally used like this:
+
+    \code
+    QUrl url( "http://www.trolltech.com" );
+    // or
+    QUrl url( "file:/home/myself/Mail", "Inbox" );
+    \endcode
+
+    You can then access and manipulate the various parts of the URL.
+
+    To make it easy to work with QUrls and QStrings, QUrl implements
+    the necessary cast and assignment operators so you can do
+    following:
+
+    \code
+    QUrl url( "http://www.trolltech.com" );
+    QString s = url;
+    // or
+    QString s( "http://www.trolltech.com" );
+    QUrl url( s );
+    \endcode
+
+    Use the static functions, encode() and decode() to encode or
+    decode a URL in a string. (They operate on the string in-place.)
+    The isRelativeUrl() static function returns TRUE if the given
+    string is a relative URL.
+
+    If you want to use a URL to work on a hierarchical structure (e.g.
+    a local or remote filesystem), you might want to use the subclass
+    QUrlOperator.

+}
+
+/*!
+    Constructs an URL taking \a url as the base (context) and
+    \a relUrl as a relative URL to \a url. If \a relUrl is not relative,
+    \a relUrl is taken as the new URL.
+
+    For example, the path of
+    \code
+    QUrl url( "ftp://ftp.trolltech.com/qt/source", "qt-2.1.0.tar.gz" );
+    \endcode
+    will be "/qt/srource/qt-2.1.0.tar.gz".
+
+    On the other hand,
+    \code
+    QUrl url( "ftp://ftp.trolltech.com/qt/source", "/usr/local" );
+    \endcode
+    will result in a new URL, "ftp://ftp.trolltech.com/usr/local",
+    because "/usr/local" isn't relative.
+
+    Similarly,
+    \code
+    QUrl url( "ftp://ftp.trolltech.com/qt/source", "file:/usr/local" );
+    \endcode
+    will result in a new URL, with "/usr/local" as the path
+    and "file" as the protocol.
+
+    Normally it is expected that the path of \a url points to a
+    directory, even if the path has no slash at the end. But if you
+    want the constructor to handle the last part of the path as a file
+    name if there is no slash at the end, and to let it be replaced by
+    the file name of \a relUrl (if it contains one), set \a checkSlash
+    to TRUE.
