The sprite toolkit generates image sprites.
The toolkit creates a sprite image for each any subfolder (excluding node_modules) with the PNG images found in it.
The sprite system uses sprity to generate the sprites. By default, the _build.js file uses the _config.js defaults. These options can be overwritten by sending in command line arguments.
For example to override the prefix a command line argument could be sent from NPM scripts:
-- --prefix="image-sprite"
