-# TODO:
-# * create the directory in _part too
-
-# This resource collects file snippets from a directory ($dir) and concatenates
-# them in lexical order of their names into a new file ($name). This can be
-# used to collect information from disparate sources, when the target file
-# format doesn't allow includes.
-#
-# concatenated_file_part can be used to easily configure content for this.
-#
-# If no $dir is specified, the target name with '.d' appended will be used.
-#
-# The $dir is purged by puppet and will only contain explicitely configured
-# files. This can be overridden by defining the directory before the
-# concatenated_file.
-#
-# Depend on File[$name] to change if and only if its contents change. Notify
-# Exec["concat_${name}"] if you want to force an update.
-#
-# Usage:
-# concatenated_file { "/etc/some.conf":
-# dir => "/etc/some.conf.d",
-# }
