Dockerfile

# 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.
