"""
That's the base of the rrule operation. It accepts all the keywords
defined in the RFC as its constructor parameters (except byday,
which was renamed to byweekday) and more. The constructor prototype is::
rrule(freq)
Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY,
or SECONDLY.
Additionally, it supports the following keyword arguments:
:param cache:
If given, it must be a boolean value specifying to enable or disable
caching of results. If you will use the same rrule instance multiple
times, enabling caching will improve the performance considerably.
:param dtstart:
The recurrence start. Besides being the base for the recurrence,
missing parameters in the final recurrence instances will also be
extracted from this date. If not given, datetime.now() will be used
instead.
:param interval:
The interval between each freq iteration. For example, when using
YEARLY, an interval of 2 means once every two years, but with HOURLY,
it means once every two hours. The default interval is 1.
:param wkst:
The week start day. Must be one of the MO, TU, WE constants, or an
integer, specifying the first day of the week. This will affect
recurrences based on weekly periods. The default week start is got
from calendar.firstweekday(), and may be modified by
calendar.setfirstweekday().
:param count:
How many occurrences will be generated.
:param until:
If given, this must be a datetime instance, that will specify the
limit of the recurrence. If a recurrence instance happens to be the
same as the datetime instance given in the until keyword, this will
be the last occurrence.
:param bysetpos:
If given, it must be either an integer, or a sequence of integers,
positive or negative. Each given integer will specify an occurrence
number, corresponding to the nth occurrence of the rule inside the
frequency period. For example, a bysetpos of -1 if combined with a
MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will
result in the last work day of every month.
:param bymonth:
If given, it must be either an integer, or a sequence of integers,
meaning the months to apply the recurrence to.
:param bymonthday:
If given, it must be either an integer, or a sequence of integers,
meaning the month days to apply the recurrence to.
:param byyearday:
If given, it must be either an integer, or a sequence of integers,
meaning the year days to apply the recurrence to.
:param byweekno:
If given, it must be either an integer, or a sequence of integers,
meaning the week numbers to apply the recurrence to. Week numbers
have the meaning described in ISO8601, that is, the first week of
the year is that containing at least four days of the new year.
:param byweekday:
If given, it must be either an integer (0 == MO), a sequence of
integers, one of the weekday constants (MO, TU, etc), or a sequence
of these constants. When given, these variables will define the
weekdays where the recurrence will be applied. It's also possible to
use an argument n for the weekday instances, which will mean the nth
occurrence of this weekday in the period. For example, with MONTHLY,
or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the
first friday of the month where the recurrence happens. Notice that in
the RFC documentation, this is specified as BYDAY, but was renamed to
avoid the ambiguity of that keyword.
:param byhour:
If given, it must be either an integer, or a sequence of integers,
meaning the hours to apply the recurrence to.
:param byminute:
If given, it must be either an integer, or a sequence of integers,
meaning the minutes to apply the recurrence to.
:param bysecond:
If given, it must be either an integer, or a sequence of integers,
meaning the seconds to apply the recurrence to.
:param byeaster:
If given, it must be either an integer, or a sequence of integers,
positive or negative. Each integer will define an offset from the
Easter Sunday. Passing the offset 0 to byeaster will yield the Easter
Sunday itself. This is an extension to the RFC specification.

If a `BYXXX` sequence is passed to the constructor at the same level as

specifications which cannot be reached given some starting conditions.
This occurs whenever the interval is not coprime with the base of a
given unit and the difference between the starting position and the
ending position is not coprime with the greatest common denominator
between the interval and the base. For example, with a FREQ of hourly
starting at 17:00 and an interval of 4, the only valid values for
BYHOUR would be {21, 1, 5, 9, 13, 17}, because 4 and 24 are not
coprime.
:param:`start` specifies the starting position.
:param:`byxxx` is an iterable containing the list of allowed values.
:param:`base` is the largest allowable value for the specified
frequency (e.g. 24 hours, 60 minutes).
This does not preserve the type of the iterable, returning a set, since
the values should be unique and the order is irrelevant, this will
speed up later lookups.

results in an empty rrule.
