"""The complete set of wasp-os application entry points are documented

below as part of a template application. Note that the template does

not rely on any specific parent class. This is because applications in

wasp-os can rely on *duck typing* making a class hierarchy pointless.

Applications must provide a short ``NAME`` that is used by the

launcher to describe the application. Names that are longer than

8 characters are likely to be abridged by the launcher in order

to fit on the screen.

Applications can optionally provide an icon for display by the

launcher. Applications that expect to be installed on the quick

|
ring will not be listed by the launcher and need not provide any
|
|
icon. When no icon is provided the system will use a default
|
|
icon.
|
|
|
|
The icon is an opportunity to differentiate your application from others
|

so supplying an icon is strongly recommended. The icon, when provided,

must not be larger than 96x64.
