# Copy files of example map
sudo cp -av /tmp/mod_tile_src/utils/example-map /usr/share/renderd/example-map

# Add configuration
sudo cp -av /tmp/mod_tile_src/etc/apache2/renderd-example-map.conf /etc/apache2/sites-available/renderd-example-map.conf
printf '\n[example-map]\nURI=/tiles/renderd-example\nXML=/usr/share/renderd/example-map/mapnik.xml\n' | sudo tee -a /etc/renderd.conf
