Use this script with a Nuxt Content site to emulate Hugo's use of archetypes to create new content. Easily extendable with different templates for different types of content.

# To run this script anywhere, you can remove the .py extension and make it
#   executable with `chmod +x newpost`. Move it somwhere in your PATH, like
#   /usr/local/bin. Now you can run `newpost "New blog post!"` from any
#   terminal session.
