'''
Showcase of Kivy Features
=========================
This showcases many features of Kivy. You should see a
menu bar across the top with a demonstration area below. The
first demonstration is the accordion layout. You can see, but not
edit, the kv language code for any screen by pressing the bug or
'show source' icon. Scroll through the demonstrations using the
left and right icons in the top right or selecting from the menu
bar.
The file showcase.kv describes the main container, while each demonstration
pane is described in a separate .kv file in the data/screens directory.
The image data/background.png provides the gradient background while the
icons in data/icon directory are used in the control bar. The file
data/faust_github.jpg is used in the Scatter pane. The icons are
from `http://www.gentleface.com/free_icon_set.html` and licensed as
Creative Commons - Attribution and Non-commercial Use Only; they
sell a commercial license.
The file android.txt is used to package the application for use with the
Kivy Launcher Android application. For Android devices, you can
copy/paste this directory into /sdcard/kivy/showcase on your Android device.
