-# This was a simple way to turn file names into singletons,
-#
-# The theory was, like:
-# 1. Turn filenames into singletons.
-# 2. ????
-# 3. Huge memory savings!
-#
-# In practice it used several MB more memory overall, and it cost more CPU
-# time, and it added complexity to the code.  Which was awesome.
-#
-# So, I gutted it.  It doesn't do anything any more, but we retain the
-# external form that people included so that they don't explode so much.
-#
-# This should be removed from the system after a graceful deprecation period,
-# probably about the time that a version of Puppet containing this change is
-# the last supported version. --daniel 2012-07-17
