class ViewPlugin(BasePlugin):
"""Marker class for plugins that provide views.
View plugins must have a 'urls' property which contains an iterable of pairs
or triples, like (routex string, handler class, kwargs dict). The kwargs
dict is optional. If present, the members of the kwargs dict will be passed
as keyword arguments to the constructor of the view object.
View plugins may also have a 'help' property, which should contain a dict
of dicts and help file names. This dict is then used to generate the
appropriate entries in the help system.
Tabs can also be defined by view plugins. To define tabs, provide a 'tabs'
property containing 6-tuples of (name, title, desc, icon, path, weight).
The icon should be relative to the plugin's media directory, and the path
should be relative to the root. The weight is used for ordering; larger
weights are further right.
"""

class PublicViewPlugin(BasePlugin):
"""Marker class for plugins that provide public mode views.
Public view plugins can specify the same 'urls' property as normal view
plugins, but they are added to the public mode router instead.

class OverlayPlugin(BasePlugin):

Overlay plugins provide mini-views which can be displayed on top of other
views. The canonical example of a plugin of this type is the Console plugin.

"""Marker class for plugins which provide cookies.
Cookie plugins provide a 'cookies' dict mapping names to generation
functions. The function should return the data to store in the cookie on
login. If the function is None, the cookie is not created on login, just
deleted on logout.
"""
pass
class MediaPlugin(BasePlugin):
"""Marker class for plugins which provide media files.
Media plugins provide a 'media' attribute, which is a string pointing to a
subdirectory that contains media files to be served statically.
