+class relativedelta:
+    """
+The relativedelta type is based on the specification of the excelent
+work done by M.-A. Lemburg in his mx.DateTime 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's two different ways to build a relativedelta instance. The
+first one is passing it two date/datetime classes:
+
+    relativedelta(datetime1, datetime2)
+
+And the other way is to use the following keyword arguments:
+
+    year, month, day, hour, minute, second, microsecond:
+        Absolute information.
+
+    years, months, weeks, days, hours, minutes, seconds, microseconds:
+        Relative information, may be negative.
+
+    weekday:
+        One of the weekday instances (MO, TU, etc). 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.
+
+    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.
+
+Here is the behavior of operations with relativedelta:
+
+1) Calculate the absolute year, using the 'year' argument, or the
+   original datetime year, if the argument is not present.
+
+2) Add the relative 'years' argument to the absolute year.
+
+3) Do steps 1 and 2 for month/months.
+
+4) Calculate the absolute day, using the 'day' argument, or the
+   original datetime day, if the argument is not present. Then,
+   subtract from the day until it fits in the year and month
+   found after their operations.
+
+5) Add the relative 'days' argument to the absolute day. Notice
+   that the 'weeks' argument is multiplied by 7 and added to
+   'days'.
+
+6) Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds,
+   microsecond/microseconds.
+
+7) If the 'weekday' argument is present, calculate the weekday,
+   with the given (wday, nth) tuple. wday is the index of the
+   weekday (0-6, 0=Mon), and nth is the number of weeks to add
+   forward or backward, depending on its signal. Notice that if
+   the calculated date is already Monday, for example, using
+   (0, 1) or (0, -1) won't change the day.
