# Credit to Julien Guyomard (https://github.com/jguyomard). This Dockerfile

# is essentially based on his Dockerfile at

# https://github.com/jguyomard/docker-hugo/blob/master/Dockerfile. The only significant

# change is that the Hugo version is now an overridable argument rather than a fixed

# environment variable.
