-class relativedelta(object):
-    """
-    The relativedelta type is designed to be applied to an existing datetime and
-    can replace specific components of that datetime, or represents an interval
-    of time.
-
-    It is based on the specification of the excellent work done by M.-A. Lemburg
-    in his
-    `mx.DateTime <https://www.egenix.com/products/python/mxBase/mxDateTime/>`_ extension.
-    However, notice that this type does *NOT* implement the same algorithm as
-    his work. Do *NOT* expect it to behave like mx.DateTime's counterpart.
-
-    There are two different ways to build a relativedelta instance. The
-    first one is passing it two date/datetime classes::
-
-        relativedelta(datetime1, datetime2)
-
-    The second one is passing it any number of the following keyword arguments::
-
-        relativedelta(arg1=x,arg2=y,arg3=z...)
-
-        year, month, day, hour, minute, second, microsecond:
-            Absolute information (argument is singular); adding or subtracting a
-            relativedelta with absolute information does not perform an arithmetic
-            operation, but rather REPLACES the corresponding value in the
-            original datetime with the value(s) in relativedelta.
-
-        years, months, weeks, days, hours, minutes, seconds, microseconds:
-            Relative information, may be negative (argument is plural); adding
-            or subtracting a relativedelta with relative information performs
-            the corresponding arithmetic operation on the original datetime value
-            with the information in the relativedelta.
-
-        weekday: 
-            One of the weekday instances (MO, TU, etc) available in the
-            relativedelta module. These instances may receive a parameter N,
-            specifying the Nth weekday, which could be positive or negative
-            (like MO(+1) or MO(-2)). Not specifying it is the same as specifying
-            +1. You can also use an integer, where 0=MO. This argument is always
-            relative e.g. if the calculated date is already Monday, using MO(1)
-            or MO(-1) won't change the day. To effectively make it absolute, use
-            it in combination with the day argument (e.g. day=1, MO(1) for first
-            Monday of the month).
-
-        leapdays:
-            Will add given days to the date found, if year is a leap
-            year, and the date found is post 28 of february.
-
-        yearday, nlyearday:
-            Set the yearday or the non-leap year day (jump leap days).
-            These are converted to day/month/leapdays information.
-
-    There are relative and absolute forms of the keyword
-    arguments. The plural is relative, and the singular is
-    absolute. For each argument in the order below, the absolute form
-    is applied first (by setting each attribute to that value) and
-    then the relative form (by adding the value to the attribute).
-
-    The order of attributes considered when this relativedelta is
-    added to a datetime is:
-
-    1. Year
-    2. Month
-    3. Day
-    4. Hours
-    5. Minutes
-    6. Seconds
-    7. Microseconds
-
-    Finally, weekday is applied, using the rule described above.
-
-    For example
-
-    >>> from datetime import datetime
-    >>> from dateutil.relativedelta import relativedelta, MO
-    >>> dt = datetime(2018, 4, 9, 13, 37, 0)
-    >>> delta = relativedelta(hours=25, day=1, weekday=MO(1))
-    >>> dt + delta
-    datetime.datetime(2018, 4, 2, 14, 37)
-
-    First, the day is set to 1 (the first of the month), then 25 hours
-    are added, to get to the 2nd day and 14th hour, finally the
-    weekday is applied, but since the 2nd is already a Monday there is
-    no effect.
