+What is it?
+===========
+
+A Puppet module that can construct files from fragments.
+
+Please see the comments in the various .pp files for details
+as well as posts on my blog at http://www.devco.net/
+
+Released under the Apache 2.0 licence
+
+Usage:
+------
+
+Before you can use any of the concat features you should include the class
+concat::setup somewhere on your node first.
+
+If you wanted a /etc/motd file that listed all the major modules
+on the machine. And that would be maintained automatically even
+if you just remove the include lines for other modules you could
+use code like below, a sample /etc/motd would be:
+
+<pre>
+Puppet modules on this server:
+
+ -- Apache
+ -- MySQL
+</pre>
+
+Local sysadmins can also append to the file by just editing /etc/motd.local
+their changes will be incorporated into the puppet managed motd.
+
+<pre>
+# class to setup basic motd, include on all nodes
+class motd {
+ include concat::setup
+ $motd = "/etc/motd"
+
+ concat{$motd:
+ owner => root,
+ group => root,
+ mode => 644
+ }
+
+ concat::fragment{"motd_header":
+ target => $motd,
+ content => "\nPuppet modules on this server:\n\n",
+ order => 01,
+ }
+
+ # local users on the machine can append to motd by just creating
+ # /etc/motd.local
+ concat::fragment{"motd_local":
+ target => $motd,
+ ensure => "/etc/motd.local",
+ order => 15
+ }
+}
+
+# used by other modules to register themselves in the motd
+define motd::register($content="", $order=10) {
+ if $content == "" {
+ $body = $name
+ } else {
+ $body = $content
+ }
+
+ concat::fragment{"motd_fragment_$name":
+ target => "/etc/motd",
+ content => " -- $body\n"
+ }
+}
+
+# a sample apache module
+class apache {
+ include apache::install, apache::config, apache::service
+
+ motd::register{"Apache": }
+}
+</pre>
+
+Known Issues:
+-------------
+* In 0.24.8 you will see inintended notifies, if you build a file
+ in a run, the next run will also see it as changed. This is due
+ to how 0.24.8 does the purging of unhandled files, this is improved
+ in 0.25.x and we cannot work around it in our code.
+* Since puppet-concat now relies on a fact for the concat directory,
+ you will need to set up pluginsync = true for at least the first run.
+ You have this issue if puppet fails to run on the client and you have
+ a message similar to
+ "err: Failed to apply catalog: Parameter path failed: File
+ paths must be fully qualified, not 'undef' at [...]/concat/manifests/setup.pp:44".
+
+Contributors:
+-------------
+**Paul Elliot**
+
+ * Provided 0.24.8 support, shell warnings and empty file creation support.
+
+**Chad Netzer**
+
+ * Various patches to improve safety of file operations
+ * Symlink support
+
+**David Schmitt**
+
+ * Patch to remove hard coded paths relying on OS path
+ * Patch to use file{} to copy the resulting file to the final destination. This means Puppet client will show diffs and that hopefully we can change file ownerships now
