and in iTunes Store Browser.
The (sub-)category has to be one from the values defined at
http://www.apple.com/itunes/podcasts/specs.html#categories
This method can be called with:
- the fields of an itunes_category as keyword arguments
- the fields of an itunes_category as a dictionary
- a list of dictionaries containing the itunes_category fields
An itunes_category has the following fields:
- *cat* name for a category.
- *sub* name for a subcategory, child of category
If a podcast has more than one subcategory from the same category, the
category is called more than once.
Likei the parameter::
[{"cat":"Arts","sub":"Design"},{"cat":"Arts","sub":"Food"}]
…would become::
<itunes:category text="Arts">
<itunes:category text="Design"/>
<itunes:category text="Food"/>
</itunes:category>
:param itunes_category: Dictionary or list of dictionaries with
itunes_category data.
:param replace: Add or replace old data.
:returns: List of itunes_categories as dictionaries.

the feedgen did only support one category plus one subcategory which
would be passed to this ducntion as first two parameters. For
compatibility reasons, this still works but should not be used any may
be removed at any time.

'''Get or set link data. An link element is a dict with the fields
href, rel, type, hreflang, title, and length. Href is mandatory for
ATOM.
This method can be called with:
- the fields of a link as keyword arguments
- the fields of a link as a dictionary
- a list of dictionaries containing the link fields
A link has the following fields:
- *href* is the URI of the referenced resource (typically a Web page)
- *rel* contains a single link relationship type. It can be a full URI,
or one of the following predefined values (default=alternate):
- *alternate* an alternate representation of the entry or feed, for
example a permalink to the html version of the entry, or the
front page of the weblog.
- *enclosure* a related resource which is potentially large in size
and might require special handling, for example an audio or video
recording.
- *related* an document related to the entry or feed.
- *self* the feed itself.
- *via* the source of the information provided in the entry.
- *type* indicates the media type of the resource.
- *hreflang* indicates the language of the referenced resource.
- *title* human readable information about the link, typically for
display purposes.
- *length* the length of the resource, in bytes.
RSS only supports one link with URL only.
:param link: Dict or list of dicts with data.
:param replace: If old links are to be replaced (default: False)

This method can be called with:

<media:content> is a sub-element of either <item> or <media:group>.
Media objects that are not the same content should not be included in
the same <media:group> element. The sequence of these items implies
the order of presentation. While many of the attributes appear to be
audio/video specific, this element can be used to publish any type
of media. It contains 14 attributes, most of which are optional.
media:content has the following fields:
- *url* should specify the direct URL to the media object.
- *fileSize* number of bytes of the media object.
- *type* standard MIME type of the object.
- *medium* type of object (image | audio | video | document |
executable).
- *isDefault* determines if this is the default object.
- *expression* determines if the object is a sample or the full version
of the object, or even if it is a continuous stream (sample | full |
nonstop).
- *bitrate* kilobits per second rate of media.
- *framerate* number of frames per second for the media object.
- *samplingrate* number of samples per second taken to create the media
object. It is expressed in thousands of samples per second (kHz).
- *channels* number of audio channels in the media object.
- *duration* number of seconds the media object plays.
- *height* height of the media object.
- *width* width of the media object.
- *lang* is the primary language encapsulated in the media object.
