+"""
+    croniter provides iteration for datetime object with cron like format.
+    
+    Simple example of usage is followings
+
+    >>> from croniter import croniter
+    >>> from datetime import datetime
+    >>> base = datetime(2010, 1, 25, 4, 46)
+    >>> iter = croniter('*/5 * * * *', base)  # every 5 minites
+    >>> print iter.get_next(datetime)   # 2010-01-25 04:50:00
+    >>> print iter.get_next(datetime)   # 2010-01-25 04:55:00
+    >>> print iter.get_next(datetime)   # 2010-01-25 05:00:00
+    >>>
+    >>> iter = croniter('2 4 * * mon,fri', base)  # 04:02 on every Monday and Friday
+    >>> print iter.get_next(datetime)   # 2010-01-26 04:02:00
+    >>> print iter.get_next(datetime)   # 2010-01-30 04:02:00
+    >>> print iter.get_next(datetime)   # 2010-01-25 05:00:00
+
+    All you need to know is constructor and get_next, these signature are following.
+
+    >>> def __init__(self, cron_format, start_time=time.time())
+    croniter iterate along with 'cron_format' from 'start_time'.
+    cron_format is 'min hour day month day_of_week', and please refer to
+    http://en.wikipedia.org/wiki/Cron for details.
+
+    >>> def get_next(self, ret_type=float)
+    get_next return next time in iteration with 'ret_type'.
+    And ret_type accept only 'float' or 'datetime'.
