-    Returns a valid URL from a user supplied \a userInput string if one can be
-    deducted. In the case that is not possible, an invalid QUrl() is returned.
-
-    \since 4.6
-
-    Most applications that can browse the web, allow the user to input a URL
-    in the form of a plain string. This string can be manually typed into
-    a location bar, obtained from the clipboard, or passed in via command
-    line arguments.
-
-    When the string is not already a valid URL, a best guess is performed,
-    making various web related assumptions.
-
-    In the case the string corresponds to a valid file path on the system,
-    a file:// URL is constructed, using QUrl::fromLocalFile().
-
-    If that is not the case, an attempt is made to turn the string into a
-    http:// or ftp:// URL. The latter in the case the string starts with
-    'ftp'. The result is then passed through QUrl's tolerant parser, and
-    in the case or success, a valid QUrl is returned, or else a QUrl().
-
-    \section1 Examples:
-
-    \list
-    \o qt.nokia.com becomes http://qt.nokia.com
-    \o ftp.qt.nokia.com becomes ftp://ftp.qt.nokia.com
-    \o localhost becomes http://localhost
-    \o /home/user/test.html becomes file:///home/user/test.html (if exists)
-    \endlist
-
-    \section2 Tips to avoid erroneous character conversion when dealing with
-    URLs and strings:
-
-    \list
-    \o When creating an URL QString from a QByteArray or a char*, always use
-       QString::fromUtf8().
-    \o Favor the use of QUrl::fromEncoded() and QUrl::toEncoded() instead of
-       QUrl(string) and QUrl::toString() when converting QUrl to/from string.
