+description: Writes a children's book and generates illustrations for it.
+args: story: The story to write and illustrate. Can be a prompt or a complete story.
+
+Do the following steps sequentially:
+
+1. Create a folder called story with mkdir.
+2. If ${story} is a prompt and not a complete children's story, call story-writer
+   to write a story based on the prompt.
+3. Take ${story} and break it up into logical chunks of text.
+4. For each chunk:
+   - Call story-illustrator to illustrate it.
+   - Download the illustration to a file at story/<chunk_number>.png.
+5. Compile the chunks and their illustrations into an HTML file to story/story.html where
+   the text and illustrations are side-by-side scrolling down with good padding. Make sure
+   the image is not too large and the text is not too small.
+6. Finally, call serve to serve the story as a webpage and print "Serving at http://localhost:8081".
