 ##2014-01-03 - Release 1.1.0-rc1
 ###Summary
 
 This release of concat was 90% written by Joshua Hoblitt, and the module team
 would like to thank him for the huge amount of work he put into this release.
 
 This module deprecates a bunch of old parameters and usage patterns, modernizes
 much of the manifest code, simplifies a whole bunch of logic and makes
 improvements to almost all parts of the module.
 
 The other major feature is windows support, courtesy of luisfdez, with an
 alternative version of the concat bash script in ruby.  We've attempted to
 ensure that there are no backwards incompatible changes, all users of 1.0.0
 should be able to use 1.1.0 without any failures, but you may find deprecation
 warnings and we'll be aggressively moving for a 2.0 to remove those too.
 
 For further information on deprecations, please read:
 https://github.com/puppetlabs/puppetlabs-concat/blob/master/README.md#api-deprecations
 
 ####Removed
 - Puppet 0.24 support.
 - Filebucket backup of all file resources except the target concatenated file.
 - Default owner/user/group values.
 - Purging of long unused /usr/local/bin/concatfragments.sh
 
 ###Features
 - Windows support via a ruby version of the concat bash script.
 - Huge amount of acceptance testing work added.
 - Documentation (README) completely rewritten.
 - New parameters in concat:
  - `ensure`: Controls if the file should be present/absent at all.
  - Remove requirement to include concat::setup in manifests.
  - Made `gnu` parameter deprecated.
  - Added parameter validation.
 
 ###Bugfixes
  - Ensure concat::setup runs before concat::fragment in all cases.
  - Pluginsync references updated for modern Puppet.
  - Fix incorrect group parameter.
  - Use $owner instead of $id to avoid confusion with $::id
  - Compatibility fixes for Puppet 2.7/ruby 1.8.7
  - Use LC_ALL=C instead of LANG=C
  - Always exec the concatfragments script as root when running as root.
  - Syntax and other cleanup changes.

 ##2013-08-09 - 1.0.0
 ###Summary
 
 Many new features and bugfixes in this release, and if you're a heavy concat
 user you should test carefully before upgrading.  The features should all be
 backwards compatible but only light testing has been done from our side before
 this release.
 
 ####Features

  - `replace`: specify if concat should replace existing files.
  - `ensure_newline`: controls if fragments should contain a newline at the end.
 - Improved README documentation.
 - Add rspec:system tests (rake spec:system to test concat)
 
 ####Bugfixes

 ##Overview
 
 The concat module lets you construct files from multiple ordered fragments of text.
 
 ##Module Description
 
 The concat module lets you gather `concat::fragment` resources from your other modules and order them into a coherent file through a single `concat` resource.
 
 ###Beginning with concat
 
 To start using concat you need to create:
 
 * A concat{} resource for the final file.
 * One or more concat::fragment{}s.
 
 A minimal example might be:
 
 ~~~
 concat { '/tmp/file':
   ensure => present,
 }
 
 concat::fragment { 'tmpfile':
   target  => '/tmp/file',
   content => 'test contents',
   order   => '01'
 }
 ~~~
 
 ##Usage
 
 ###Maintain a list of the major modules on a node
 
 To maintain an motd file that lists the modules on one of your nodes, first create a class to frame up the file:
 
 ~~~
 class motd {
   $motd = '/etc/motd'
 
   concat { $motd:
     owner => 'root',
     group => 'root',
     mode  => '0644'
   }
 
   concat::fragment{ 'motd_header':
     target  => $motd,
     content => "\nPuppet modules on this server:\n\n",
     order   => '01'
   }
 
   # let local users add to the motd by creating a file called
   # /etc/motd.local
   concat::fragment{ 'motd_local':
     target => $motd,
     source => '/etc/motd.local',
     order  => '15'
   }
 }
 
 # let other modules register themselves in the motd
 define motd::register($content="", $order='10') {
   if $content == "" {
     $body = $name
   } else {
     $body = $content
   }
 
   concat::fragment{ "motd_fragment_$name":
     target  => '/etc/motd',
     order   => $order,
     content => "    -- $body\n"
   }
 }
 ~~~
 
 Then, in the declarations for each module on the node, add `motd::register{ 'Apache': }` to register the module in the motd.
 
 ~~~
 class apache {
   include apache::install, apache::config, apache::service
 
   motd::register{ 'Apache': }
 }
 ~~~
 
 These two steps populate the /etc/motd file with a list of the installed and registered modules, which stays updated even if you just remove the registered modules' `include` lines. System administrators can append text to the list by writing to /etc/motd.local.
 
 When you're finished, the motd file will look something like this:
 
 ~~~
   Puppet modules on this server:
 
     -- Apache
     -- MySQL
 
   <contents of /etc/motd.local>
 ~~~

 ###Parameters
 
 ####Define: `concat`
 
 All the parameters listed below are optional.
 
 #####`backup`
 
 Specifies whether (and how) to back up the destination file before overwriting it. Your value gets passed on to Puppet's [native `file` resource](https://docs.puppetlabs.com/references/latest/type.html#file-attribute-backup) for execution. Valid options: 'true', 'false', or a string representing either a target filebucket or a filename extension beginning with ".". Default value: 'puppet'.
 
 #####`ensure`
 
 Specifies whether the destination file should exist. Setting to 'absent' tells Puppet to delete the destination file if it exists, and negates the effect of any other parameters. Valid options: 'present' and 'absent'. Default value: 'present'.
 
 #####`ensure_newline`
 
 Specifies whether to add a line break at the end of each fragment that doesn't already end in one. Valid options: 'true' and 'false'. Default value: 'false'.
 
 #####`force`
 
 Deprecated as of concat v2.0.0. Has no effect.
 
 #####`group`
 
 Specifies a permissions group for the destination file. Valid options: a string containing a group name. Default value: undefined.
 
 #####`mode`
 
 Specifies the permissions mode of the destination file. Valid options: a string containing a permission mode value in octal notation. Default value: '0644'.
 
 #####`order`
 
 Specifies a method for sorting your fragments by name within the destination file. Valid options: 'alpha' (e.g., '1, 10, 2') or 'numeric' (e.g., '1, 2, 10'). Default value: 'alpha'.
 
 You can override this setting for individual fragments by adjusting the `order` parameter in their `concat::fragment` declarations.
 
 #####`owner`
 
 Specifies the owner of the destination file. Valid options: a string containing a username. Default value: undefined.
 
 #####`path`
 
 Specifies a destination file for the combined fragments. Valid options: a string containing an absolute path. Default value: the title of your declared resource.
 
 #####`replace`
 
 Specifies whether to overwrite the destination file if it already exists. Valid options: 'true' and 'false'. Default value: 'true'.
 
 #####`validate_cmd`
 
 Specifies a validation command to apply to the destination file. Requires Puppet version 3.5 or newer. Valid options: a string to be passed to a file resource. Default value: undefined.
 
 #####`warn`
 
 Specifies whether to add a header message at the top of the destination file. Valid options: the booleans 'true' and 'false', or a string to serve as the header. Default value: 'false'.
 
 If you set 'warn' to 'true', `concat` adds the following line with an `order` of `0`:
 
 ~~~
 # This file is managed by Puppet. DO NOT EDIT.
 ~~~
 
 Before 2.0.0, this parameter would add a newline at the end of the warn
 message. To improve flexibilty, this was removed. Please add it explicitely if
 you need it.

Valid options: 'true', 'false', or a string representing either a target filebucket or a filename extension beginning with ".". Default value: 'puppet'.
 
 #####`ensure`
 
 Specifies whether the destination file should exist. Setting to 'absent' tells Puppet to delete the destination file if it exists, and negates the effect of any other parameters. Valid options: 'present' and 'absent'. Default value: 'present'.
 
 #####`ensure_newline`
 
 Specifies whether to add a line break at the end of each fragment that doesn't already end in one. Valid options: 'true' and 'false'. Default value: 'false'.

 #####`path`
 
 Specifies a destination file for the combined fragments. Valid options: a string containing an absolute path. Default value: the title of your declared resource.
 
 #####`replace`

 ###Removed functionality
 
 The following functionality existed in previous versions of the concat module, but was removed in version 2.0.0:
 
 Parameters removed from `concat::fragment`:
 * `gnu`
 * `backup`
 * `group`
 * `mode`
 * `owner`
 
 The `concat::setup` class has also been removed.
 
 Prior to concat version 2.0.0, if you set the `warn` parameter to a string value of 'true', 'false', 'yes', 'no', 'on', or 'off', the module translated the string to the corresponding boolean value. In concat version 2.0.0 and newer, the `warn_header` parameter treats those values the same as other strings and uses them as the content of your header message. To avoid that, pass the 'true' and 'false' values as booleans instead of strings.
 
 ##Limitations
 
 This module has been tested on [all PE-supported platforms](https://forge.puppetlabs.com/supported#compat-matrix), and no issues have been identified.
 
 ##Development
 
 Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.
 
 We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
 
 For more information, see our [module contribution guide.](https://docs.puppetlabs.com/forge/contributing.html)

 # [*ensure*]
 #   Present/Absent
 # [*path*]
 #   The path to the final file. Use this in case you want to differentiate

 # [*owner*]
 #   Who will own the file
 # [*group*]
 #   Who will own the file
 # [*mode*]
 #   The mode of the final file
 # [*warn*]
 #   Adds a normal shell style comment top of the file indicating that it is
 #   built by puppet.
 #   Before 2.0.0, this parameter would add a newline at the end of the warn
 #   message. To improve flexibilty, this was removed. Please add it explicitely
 #   if you need it.
 # [*backup*]
 #   Controls the filebucketing behavior of the final file and see File type
 #   reference for its use.  Defaults to 'puppet'
 # [*replace*]
 #   Whether to replace a file that already exists on the local system
 # [*order*]
 #   Select whether to order associated fragments by 'alpha' or 'numeric'.
 #   Defaults to 'alpha'.
 # [*ensure_newline*]
 #   Specifies whether to ensure there's a new line at the end of each fragment.
 #   Valid options: 'true' and 'false'. Default value: 'false'.
 # [*validate_cmd*]
 #   Specifies a validation command to apply to the destination file.
 #   Requires Puppet version 3.5 or newer. Valid options: a string to be passed
 #   to a file resource. Default value: undefined.
