# An example application to demonstrate colours, cursor and interface movement,
# maximising/unmaximising of interfaces and toggling of cursors and interfaces.
#
# If you have cloned this repository from GitHub, you can run this example:
#
#     ./examples/material_colours_app.rb
#
# Running this application once, and immediately exiting produces the diagram
# at `./examples/material_colours_app_20150721.svg`. Hopefully this will help
# you to understand how parts of Vedeu work together. Questions are always
# welcome at `https://github.com/gavinlaking/vedeu/issues`
