run_all.rb

# frozen_string_literal: true

# Runs every example in examples/*/run.rb, in order.
# --verify additionally checks each example's required output markers.
#
# Usage:
#   ruby run_all.rb            # runs every example
#   ruby run_all.rb --verify   # same, plus runs every example's verify.rb
