+This libray consists of a group of classes which allow KDE 
+applications to access calendar dates outside of the limited range 
+of years imposed by QDate.
+
+The QDate class has a limited range of valid dates.  It does not 
+recognize dates prior to 14 Oct 1752 (when the Gregorian calendar 
+was adopted by England), nor dates after 31 Dec 8000.  Both of these 
+limits are arbitrary.
+
+
+The following classes are included:
+
+ExtDate:  Replaces QDate.  There is no restriction on what dates 
+may be entered.  For dates in the valid QDate range, it is 
+completely equivalent to QDate.
+
+ExtDateTime:  Replaces QDateTime.  Consists of a QTime object
+and an ExtDate object.
+
+ExtCalendarSystem:  Replaces KCalendarSystem.  Uses ExtDate instead
+of QDate.  ExtCalendarSystem is a baseclass foundation for several 
+different calendar systems.  A "calendar system" is just a method for
+hierarchically subdividing the long count of days known as the Julian 
+Day Calendar into groups (weeks, months, years).  
+
+ExtCalendarSystemGregorian:  Replaces KCalendarSystemGregorian.
+The most common calendar system in modern western societies is the 
+Gregorian calendar.  This class implements the Gregorian calendar 
+as a ExtCalendarSystem.
+
+ExtDateTable:  Replaces KDateTable.
+ExtDatePicker:  Replaces KDatePicker.
+ExtDateTimeEdit: Replaces QDateTimeEdit.
+ExtDateWidget:  Replaces KDateWidget.
+
+There are two test programs with the library, to verify the 
+functionality of the ExtDate classes:
+
+test_extdate tests the non-GUI functionality, comparing results of 
+several operations with the results from QDate.
+
+test_extdatepicker presents a KDatePicker widget and an ExtDatePicker
+widget side-by-side.

+/*!
+    \class ExtDateTime extdatetime.h
+    \brief The ExtDateTime class provides date and time functions.
+
+    \ingroup time
+
+    A ExtDateTime object contains a calendar date and a clock time (a
+    "datetime"). It is a combination of the ExtDate and TQTime classes.
+    It can read the current datetime from the system clock. It
+    provides functions for comparing datetimes and for manipulating a
+    datetime by adding a number of seconds, days, months or years.
+
+    A ExtDateTime object is typically created either by giving a date
+    and time explicitly in the constructor, or by using the static
+    function tqcurrentDateTime(), which returns a ExtDateTime object set
+    to the system clock's time. The date and time can be changed with
+    setDate() and setTime(). A datetime can also be set using the
+    setTime_t() function, which takes a POSIX-standard "number of
+    seconds since 00:00:00 on January 1, 1970" value. The fromString()
+    function returns a ExtDateTime given a string and a date format
+    which is used to interpret the date within the string.
+
+    The date() and time() functions provide access to the date and
+    time parts of the datetime. The same information is provided in
+    textual format by the toString() function.
+
+    ExtDateTime provides a full set of operators to compare two
+    ExtDateTime objects where smaller means earlier and larger means
+    later.
+
+    You can increment (or decrement) a datetime by a given number of
+    seconds using addSecs() or days using addDays(). Similarly you can
+    use addMonths() and addYears(). The daysTo() function returns the
+    number of days between two datetimes, and secsTo() returns the
+    number of seconds between two datetimes.
+
+    The range of a datetime object is constrained to the ranges of the
+    ExtDate and TQTime objects which it embodies.
+
+    Methods in this class are reentrant.

+    \brief The ExtDateEdit class provides a date editor.
+
+    \ingroup advanced
+    \ingroup time
+
+    ExtDateEdit allows the user to edit dates by using the keyboard or
+    the arrow keys to increase/decrease date values. The arrow keys
+    can be used to move from section to section within the ExtDateEdit
+    box. Dates appear in accordance with the local date/time settings
+    or in year, month, day order if the system doesn't provide this
+    information. It is recommended that the ExtDateEdit be initialised
+    with a date, e.g.
+
+    \code
+    ExtDateEdit *dateEdit = new ExtDateEdit( ExtDate::tqcurrentDate(), this );
+    dateEdit->setRange( ExtDate::tqcurrentDate().addDays( -365 ),
+			ExtDate::tqcurrentDate().addDays(  365 ) );
+    dateEdit->setOrder( ExtDateEdit::MDY );
+    dateEdit->setAutoAdvance( TRUE );
+    \endcode
+
+    Here we've created a new ExtDateEdit object initialised with today's
+    date and restricted the valid date range to today plus or minus
+    365 days. We've set the order to month, day, year. If the auto
+    advance property is TRUE (as we've set it here) when the user
+    completes a section of the date, e.g. enters two digits for the
+    month, they are automatically taken to the next section.
+
+    The maximum and minimum values for a date value in the date editor
+    default to the maximum and minimum values for a ExtDate. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A ExtDateEdit widget comprises three 'sections', one
+    each for the year, month and day. You can change the separator
+    character using ExtDateTimeEditor::setSeparator(), by default the
+    separator will be taken from the systems settings. If that is
+    not possible, it defaults to "-".

+    \class TQTimeEdit ExtDatetimeedit.h
+    \brief The TQTimeEdit class provides a time editor.
+
+    \ingroup advanced
+    \ingroup time
+    \mainclass
+
+    TQTimeEdit allows the user to edit times by using the keyboard or
+    the arrow keys to increase/decrease time values. The arrow keys
+    can be used to move from section to section within the TQTimeEdit
+    box. The user can automatically be moved to the next section once
+    they complete a section using setAutoAdvance(). Times appear in
+    hour, minute, second order. It is recommended that the TQTimeEdit
+    is initialised with a time, e.g.
+    \code
+    TQTime timeNow = TQTime::currentTime();
+    TQTimeEdit *timeEdit = new TQTimeEdit( timeNow, this );
+    timeEdit->setRange( timeNow, timeNow.addSecs( 60 * 60 ) );
+    \endcode
+    Here we've created a TQTimeEdit widget set to the current time.
+    We've also set the minimum value to the current time and the
+    maximum time to one hour from now.
+
+    The maximum and minimum values for a time value in the time editor
+    default to the maximum and minimum values for a TQTime. You can
+    change this by calling setMinValue(), setMaxValue() or setRange().
+
+    Terminology: A TQTimeWidget consists of three sections, one each
+    for the hour, minute and second. You can change the separator
+    character using setSeparator(), by default the separator is read
+    from the system's settings.

+    \class ExtDateTimeEdit ExtDatetimeedit.h
+    \brief The ExtDateTimeEdit class combines a ExtDateEdit and TQTimeEdit
+    widget into a single widget for editing datetimes.
+
+    \ingroup advanced
+    \ingroup time
+
+    ExtDateTimeEdit consists of a ExtDateEdit and TQTimeEdit widget placed
+    side by side and offers the functionality of both. The user can
+    edit the date and time by using the keyboard or the arrow keys to
+    increase/decrease date or time values. The Tab key can be used to
+    move from section to section within the ExtDateTimeEdit widget, and
+    the user can be moved automatically when they complete a section
+    using setAutoAdvance(). The datetime can be set with
+    setDateTime().
+
+    The date format is read from the system's locale settings. It is
+    set to year, month, day order if that is not possible. See
+    ExtDateEdit::setOrder() to change this. Times appear in the order
+    hours, minutes, seconds using the 24 hour clock.
+
+    It is recommended that the ExtDateTimeEdit is initialised with a
+    datetime, e.g.
+    \code
+    ExtDateTimeEdit *dateTimeEdit = new ExtDateTimeEdit( ExtDateTime::tqcurrentDateTime(), this );
+    dateTimeEdit->dateEdit()->setRange( ExtDateTime::tqcurrentDate(),
+					ExtDateTime::tqcurrentDate().addDays( 7 ) );
+    \endcode
+    Here we've created a new ExtDateTimeEdit set to the current date and
+    time, and set the date to have a minimum date of now and a maximum
+    date of a week from now.
+
+    Terminology: A ExtDateEdit widget consists of three 'sections', one
+    each for the year, month and day. Similarly a TQTimeEdit consists
+    of three sections, one each for the hour, minute and second. The
+    character that separates each date section is specified with
+    setDateSeparator(); similarly setTimeSeparator() is used for the
+    time sections.
