# Demonstration of inspecting all the routes, including those on sub-apps,
# from the default app instance.
#
# This should be run directly to print a list of route prefixes and the rules.
# Tested with Python 2.7 and Bottle-dev. Patch here
# https://github.com/davidwtbuxton/bottle/commit/ddd712ef252b06ecd0e957f8ac4e37b65ee79cae
