+# This Makefile is destined to ease the work with the infrastructure repo,
+# especially when working with Vagrant: It contains wildcard targets for the
+# most common Vagrant commands ($box.$operation) that ensure each operation
+# is logged properly. This eases reporting, reproducing and debugging any
+# issues that may arise.
+# In addition, there are a set of additional targets that perform actions
+# specific to the repo, such as invocation of the ensure_dependencies.py 
+# script and the creation of the modules/private resource when necessary.
+# -------------------------------------------------------------------------
+
+# Phony targets are always considered out-of-date.
