# Targets intended for use on the command line
#
# all (default)	-	generate the releases.toml and compile all the website
# run	-			serves the built website for local browsing
#
# The run target uses hugo's built-in webserver to make the built website
# available for local browsing.  The website should have been built prior
# to attempting to use the `run` target.  By default, hugo will start its
# webserver on port 1313.
