+# A system to construct files using fragments from other files or templates.
+#
+# This requires at least puppet 0.25 to work correctly as we use some
+# enhancements in recursive directory management and regular expressions
+# to do the work here.
+#
+# USAGE:
+# The basic use case is as below:
+#
+# concat{"/etc/named.conf":
+# notify => Service["named"]
+# }
+#
+# concat::fragment{"foo.com_config":
+# target => "/etc/named.conf",
+# order => 10,
+# content => template("named_conf_zone.erb")
+# }
+#
+# # add a fragment not managed by puppet so local users
+# # can add content to managed file
+# concat::fragment{"foo.com_user_config":
+# target => "/etc/named.conf",
+# order => 12,
+# ensure => "/etc/named.conf.local"
+# }
+#
+# This will use the template named_conf_zone.erb to build a single
+# bit of config up and put it into the fragments dir. The file
+# will have an number prefix of 10, you can use the order option
+# to control that and thus control the order the final file gets built in.
+#
+# SETUP:
+# The class concat::setup uses the fact concat_basedir to define the variable
+# $concatdir, where all the temporary files and fragments will be
+# durably stored. The fact concat_basedir will be set up on the client to
+# <Puppet[:vardir]>/concat, so you will be able to run different setup/flavours
+# of puppet clients.
+# However, since this requires the file lib/facter/concat_basedir.rb to be
+# deployed on the clients, so you will have to set "pluginsync = true" on
+# both the master and client, at least for the first run.
+#
+# There's some regular expression magic to figure out the puppet version but
+# if you're on an older 0.24 version just set $puppetversion = 24
+#
+# Before you can use any of the concat features you should include the
+# class concat::setup somewhere on your node first.
+#
+# DETAIL:
+# We use a helper shell script called concatfragments.sh that gets placed
+# in <Puppet[:vardir]>/concat/bin to do the concatenation. While this might
+# seem more complex than some of the one-liner alternatives you might find on
+# the net we do a lot of error checking and safety checks in the script to avoid
+# problems that might be caused by complex escaping errors etc.

+# Sets up so that you can use fragments to build a final config file,
+#
+# OPTIONS:
+# - mode The mode of the final file
+# - owner Who will own the file
+# - group Who will own the file
+# - force Enables creating empty files if no fragments are present
+# - warn Adds a normal shell style comment top of the file indicating
+# that it is built by puppet
+# - backup Controls the filebucketing behavior of the final file and
+# see File type reference for its use. Defaults to 'puppet'
+#
+# ACTIONS:
+# - Creates fragment directories if it didn't exist already
+# - Executes the concatfragments.sh script to build the final file, this script will create
+# directory/fragments.concat. Execution happens only when:
+# * The directory changes
+# * fragments.concat != final destination, this means rebuilds will happen whenever
+# someone changes or deletes the final file. Checking is done using /usr/bin/cmp.
+# * The Exec gets notified by something else - like the concat::fragment define
+# - Copies the file over to the final destination using a file resource
+#
+# ALIASES:
+# - The exec can notified using Exec["concat_/path/to/file"] or Exec["concat_/path/to/directory"]
+# - The final file can be referened as File["/path/to/file"] or File["concat_/path/to/file"]
