+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.
