# This script places the things described in furnashings/things.json
# onto floor_plan_cleanup/cleaned_up.svg to produce a static
# floor_plan.svg file.  This is an interim measure until I can get
# things running as a web service.

# Now that placement.js is working, this script is no longer needed.
