# Demonstrates three approaches to UPDATE routing in Fractal Architecture.
#
# == Usage
#
#   ruby app.rb           # Defaults to 'manual'
#   ruby app.rb manual    # Verbose pattern matching
#   ruby app.rb helpers   # Tea.route and Tea.delegate helpers
#   ruby app.rb router    # Tea::Router DSL
#
# All three share the same bags, Model, INITIAL, and VIEW. Only the UPDATE
# implementation differs. Compare the three update_*.rb files to see the
# progression from verbose to declarative.
#
