# The help target prints out all targets with their descriptions organized

# beneath their categories. The categories are represented by '##@' and the

# target descriptions by '##'. The awk commands is responsible for reading the

# entire set of makefiles included in this invocation, looking for lines of the

# file as xyz: ## something, and then pretty-format the target and help. Then,

# if there's a line with ##@ something, that gets pretty-printed as a category.
