+VObject Overview
+================
+    vobject parses vCard or vCalendar files, returning a tree of Python objects.
+    It also provids an API to create vCard or vCalendar data structures which
+    can then be serialized.
+
+    Parsing existing streams
+    ------------------------
+    Streams containing one or many L{Component<base.Component>}s can be
+    parsed using L{readComponents<base.readComponents>}.  As each Component
+    is parsed, vobject will attempt to give it a L{Behavior<behavior.Behavior>}.
+    If an appropriate Behavior is found, any base64, quoted-printable, or
+    backslash escaped data will automatically be decoded.  Dates and datetimes
+    will be transformed to datetime.date or datetime.datetime instances.
+    Components containing recurrence information will have a special rruleset
+    attribute (a dateutil.rrule.rruleset instance).
+
+    Validation
+    ----------
+    L{Behavior<behavior.Behavior>} classes implement validation for
+    L{Component<base.Component>}s.  To validate, an object must have all
+    required children.  There (TODO: will be) a toggle to raise an exception or
+    just log unrecognized, non-experimental children and parameters.
+    
+    Creating objects programatically
+    --------------------------------
+    A L{Component<base.Component>} can be created from scratch.  No encoding
+    is necessary, serialization will encode data automatically.  Factory
+    functions (TODO: will be) available to create standard objects.
+
+    Serializing objects
+    -------------------
+    Serialization: 
+      - Looks for missing required children that can be automatically generated,
+        like a UID or a PRODID, and adds them
+      - Encodes all values that can be automatically encoded
+      - Checks to make sure the object is valid (unless this behavior is
+        explicitly disabled)
+      - Appends the serialized object to a buffer, or fills a new
+        buffer and returns it
+    
+    Examples
+    --------
+    
+    >>> import datetime
+    >>> import dateutil.rrule as rrule
+    >>> x = iCalendar()
+    >>> x.add('vevent')
+    <VEVENT| []>
+    >>> x
+    <VCALENDAR| [<VEVENT| []>]>
+    >>> v = x.vevent
+    >>> utc = icalendar.utc
+    >>> v.add('dtstart').value = datetime.datetime(2004, 12, 15, 14, tzinfo = utc)
+    >>> v
+    <VEVENT| [<DTSTART{}2004-12-15 14:00:00+00:00>]>
+    >>> x
+    <VCALENDAR| [<VEVENT| [<DTSTART{}2004-12-15 14:00:00+00:00>]>]>
+    >>> newrule = rrule.rruleset()
+    >>> newrule.rrule(rrule.rrule(rrule.WEEKLY, count=2, dtstart=v.dtstart.value))
+    >>> v.rruleset = newrule
+    >>> list(v.rruleset)
+    [datetime.datetime(2004, 12, 15, 14, 0, tzinfo=tzutc()), datetime.datetime(2004, 12, 22, 14, 0, tzinfo=tzutc())]
+    >>> v.add('uid').value = "randomuid@MYHOSTNAME"
+    >>> print x.serialize()
