 ##@ General
 
-# 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 command 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-formatting the target and help. Then,
-# if there's a line with ##@ something, that gets pretty-printed as a category.
