# Example: Using RCM with Rake (from a project directory).
#
# Run with:
#   rake setup -- --dry      # dry run, no changes made
#   rake setup -- --debug    # verbose output
#   rake setup               # apply configuration
#
# This example assumes rcm is available via bundler (see Gemfile),
# or you can swap the require for: require_relative '../../lib/dsl'
require 'rcm'
