 This script creates a gh-pages directory with the same structure as public/

 - No .json file extensions (to match API routes)
-- conda.json -> conda-map (to avoid /conda conflicts with /conda/{plugin_name})
+- conda.json -> conda_map (to avoid /conda conflicts with /conda/{plugin_name})
 - Everything nested under an 'api' directory
 - Simple index.html at the root
