-    \class TQSettings
-    \brief The TQSettings class provides persistent platform-independent application settings.
-
-    \ingroup io
-    \ingroup misc
-    \mainclass
-
-    On Unix systems, TQSettings uses text files to store settings. On Windows
-    systems, TQSettings uses the system registry.  On Mac OS X, TQSettings uses
-    the Carbon preferences API.
-
-    Each setting comprises an identifying key and the data associated with
-    the key. A key is a tqunicode string which consists of \e two or more
-    subkeys. A subkey is a slash, '/', followed by one or more tqunicode
-    characters (excluding slashes, newlines, carriage returns and equals,
-    '=', signs). The associated data, called the entry or value, may be a
-    boolean, an integer, a double, a string or a list of strings. Entry
-    strings may contain any tqunicode characters.
-
-    If you want to save and restore the entire desktop's settings, i.e.
-    which applications are running, use TQSettings to save the settings
-    for each individual application and TQSessionManager to save the
-    desktop's session.
-
-    Example settings:
-    \code
-    /MyCompany/MyApplication/background color
-    /MyCompany/MyApplication/foreground color
-    /MyCompany/MyApplication/tqgeometry/x
-    /MyCompany/MyApplication/tqgeometry/y
-    /MyCompany/MyApplication/tqgeometry/width
-    /MyCompany/MyApplication/tqgeometry/height
-    /MyCompany/MyApplication/recent files/1
-    /MyCompany/MyApplication/recent files/2
-    /MyCompany/MyApplication/recent files/3
-    \endcode
-    Each line above is a complete key, made up of subkeys.
-
-    A typical usage pattern for reading settings at application
-    startup:
-    \code
-    TQSettings settings;
-    settings.setPath( "MyCompany.com", "MyApplication" );
-
-    TQString bgColor = settings.readEntry( "/colors/background", "white" );
-    int width = settings.readNumEntry( "/tqgeometry/width", 640 );
-    // ...
-    \endcode
-
-    A typical usage pattern for saving settings at application exit or
-    'save preferences':
-    \code
-    TQSettings settings;
-    settings.setPath( "MyCompany.com", "MyApplication" );
-
-    settings.writeEntry( "/colors/background", bgColor );
-    settings.writeEntry( "/tqgeometry/width", width );
-    // ...
-    \endcode
-
-    A key prefix can be prepended to all keys using beginGroup(). The
-    application of the prefix is stopped using endGroup(). For
-    example:
-    \code
-    TQSettings settings;
-
-    settings.beginGroup( "/MainWindow" );
-        settings.beginGroup( "/Geometry" );
-            int x = settings.readEntry( "/x" );
-            // ...
-        settings.endGroup();
-        settings.beginGroup( "/Toolbars" );
-            // ...
-        settings.endGroup();
-    settings.endGroup();
-    \endcode
-
-    You can get a list of entry-holding keys by calling entryList(), and
-    a list of key-holding keys using subkeyList().
-
-    \code
-    TQStringList keys = settings.entryList( "/MyApplication" );
-    // keys contains 'background color' and 'foreground color'.
-
-    TQStringList keys = settings.entryList( "/MyApplication/recent files" );
-    // keys contains '1', '2' and '3'.
-
-    TQStringList subkeys = settings.subkeyList( "/MyApplication" );
-    // subkeys contains 'tqgeometry' and 'recent files'
-
-    TQStringList subkeys = settings.subkeyList( "/MyApplication/recent files" );
-    // subkeys is empty.
-    \endcode
-
-    Since settings for Windows are stored in the registry there are
-    some size limitations as follows:
-    \list
-    \i A subkey may not exceed 255 characters.
-    \i An entry's value may not exceed 16,300 characters.
-    \i All the values of a key (for example, all the 'recent files'
-    subkeys values), may not exceed 65,535 characters.
-    \endlist
-
-    These limitations are not enforced on Unix or Mac OS X.
-
-    \warning Creating multiple, simultaneous instances of TQSettings writing
-    to a text file may lead to data loss! This is a known issue which will
-    be fixed in a future release of TQt.
-
-    \section1 Notes for Mac OS X Applications
-
-    The location where settings are stored is not formally defined by
-    the CFPreferences API.
-
-    At the time of writing settings are stored (either on a global or
-    user basis, preferring locally) into a plist file in \c
-    $ROOT/System/Library/Preferences (in XML format). TQSettings will
-    create an appropriate plist file (\c{com.<first group name>.plist})
-    out of the full path to a key.
-
-    For further information on CFPreferences see
-    \link http://developer.apple.com/documentation/CoreFoundation/Conceptual/CFPreferences/index.html
-    Apple's Specifications\endlink
-
-    \section1 Notes for Unix Applications
-
-    There is no universally accepted place for storing application
-    settings under Unix. In the examples the settings file will be
-    searched for in the following directories:
-    \list 1
-    \i \c SYSCONF - the default value is \c INSTALL/etc/settings
-    \i \c /opt/MyCompany/share/etc
-    \i \c /opt/MyCompany/share/MyApplication/etc
-    \i \c $HOME/.qt
-    \endlist
-    When reading settings the files are searched in the order shown
-    above, with later settings overriding earlier settings. Files for
-    which the user doesn't have read permission are ignored. When saving
-    settings TQSettings works in the order shown above, writing
-    to the first settings file for which the user has write permission.
-    (\c INSTALL is the directory where TQt was installed.  This can be
-    modified by using the configure script's -prefix argument )
-
-    If you want to put the settings in a particular place in the
-    filesystem you could do this:
-    \code
-    settings.insertSearchPath( TQSettings::Unix, "/opt/MyCompany/share" );
-    \endcode
-
-    But in practice you may prefer not to use a search path for Unix.
-    For example the following code:
-    \code
-    settings.writeEntry( "/MyApplication/tqgeometry/width", width );
-    \endcode
-    will end up writing the "tqgeometry/width" setting to the file
-    \c{$HOME/.qt/myapplicationrc} (assuming that the application is
-    being run by an ordinary user, i.e. not by root).
-
-    For cross-platform applications you should ensure that the
-    \link #sizelimit Windows size limitations \endlink are not exceeded.
-
-    \warning TQSettings doesn't write the settings until it is destroyed so
-    you should construct the TQSettings object on the stack.

-/*!
-  Inserts \a path into the settings search path. The semantics of \a
-  path depends on the system \a s. It is usually easier and better to
-  use setPath() instead of this function.
-
-  When \a s is \e Windows and the execution environment is \e not
-  Windows the function does nothing. Similarly when \a s is \e Unix and
-  the execution environment is \e not Unix the function does nothing.
-
-  When \a s is \e Windows, and the execution environment is Windows, the
-  search path list will be used as the first subfolder of the "Software"
-  folder in the registry.
-
-  When reading settings the folders are searched forwards from the
-  first folder (listed below) to the last, returning the first
-  settings found, and ignoring any folders for which the user doesn't
-  have read permission.
-  \list 1
-  \i HKEY_CURRENT_USER/Software/MyCompany/MyApplication
-  \i HKEY_LOCAL_MACHINE/Software/MyCompany/MyApplication
-  \i HKEY_CURRENT_USER/Software/MyApplication
-  \i HKEY_LOCAL_MACHINE/Software/MyApplication
-  \endlist
-
-  \code
-  TQSettings settings;
-  settings.insertSearchPath( TQSettings::Windows, "/MyCompany" );
-  settings.writeEntry( "/MyApplication/Tip of the day", TRUE );
-  \endcode
-  The code above will write the subkey "Tip of the day" into the \e
-  first of the registry folders listed below that is found and for
-  which the user has write permission.
-  \list 1
-  \i HKEY_LOCAL_MACHINE/Software/MyCompany/MyApplication
-  \i HKEY_CURRENT_USER/Software/MyCompany/MyApplication
-  \i HKEY_LOCAL_MACHINE/Software/MyApplication
-  \i HKEY_CURRENT_USER/Software/MyApplication
-  \endlist
-  If a setting is found in the HKEY_CURRENT_USER space, this setting
-  is overwritten independently of write permissions in the
-  HKEY_LOCAL_MACHINE space.
-
-  When \a s is \e Unix, and the execution environment is Unix, the
-  search path list will be used when trying to determine a suitable
-  filename for reading and writing settings files. By default, there are
-  two entries in the search path:
-
-  \list 1
-  \i \c SYSCONF - where \c SYSCONF is a directory specified when
-  configuring TQt; by default it is INSTALL/etc/settings.
-  \i \c $HOME/.qt/ - where \c $HOME is the user's home directory.
-  \endlist
-
-  All insertions into the search path will go before $HOME/.qt/.
-  For example:
-  \code
-  TQSettings settings;
-  settings.insertSearchPath( TQSettings::Unix, "/opt/MyCompany/share/etc" );
-  settings.insertSearchPath( TQSettings::Unix, "/opt/MyCompany/share/MyApplication/etc" );
-  // ...
-  \endcode
-  Will result in a search path of:
-  \list 1
-  \i SYSCONF
-  \i /opt/MyCompany/share/etc
-  \i /opt/MyCompany/share/MyApplication/etc
-  \i $HOME/.qt
-  \endlist
-    When reading settings the files are searched in the order shown
-    above, with later settings overriding earlier settings. Files for
-    which the user doesn't have read permission are ignored. When saving
-    settings TQSettings works in the order shown above, writing
-    to the first settings file for which the user has write permission.
-
-    Note that paths in the file system are not created by this
-    function, so they must already exist to be useful.
-
-  Settings under Unix are stored in files whose names are based on the
-  first subkey of the key (not including the search path). The algorithm
-  for creating names is essentially: lowercase the first subkey, replace
-  spaces with underscores and add 'rc', e.g.
-  <tt>/MyCompany/MyApplication/background color</tt> will be stored in
-  <tt>myapplicationrc</tt> (assuming that <tt>/MyCompany</tt> is part of
-  the search path).
