# This script merges a template HTML file (floor_plan.html), the
# cleaned up SVG file (floor_plan_cleanup/cleaned_up.svg), javascript
# code to place things onto the floor plan (placement.js) and the data
# file (furnashings/things.json) into a single HTML file which shows
# and lists the things.

# This script is made obsolete by a working version of placement.js.
