+# This Makefile offers convience shortcuts into any Node.js project that utilizes npm scripts.
+# It functions as a wrapper around the actual listed in `package.json`
+# So instead of typing:
+#
+#  $ npm script build:assets
+#
+# you could also type:
+#
+#  $ make build-assets
+#
+# Notice that colons (:) are replaced by dashes for Makefile compatibility.
+#
+# The benefits of this wrapper are:
+#
+# - You get to keep the the scripts package.json, which is more portable
+#   (Makefiles & Windows are harder to mix)
+# - Offer a polite way into the project for developers coming from different
+#   languages (npm scripts is obviously very Node centric)
+# - Profit from better autocomplete (make <TAB><TAB>) than npm currently offers.
+#   OSX users will have to install bash-completion
+#   (http://davidalger.com/development/bash-completion-on-os-x-with-brew/)
