 ### Features
 
-Stuff that should probably be included in every configuration management,
+ * Elegant code and clean design
-but is not. Or: Why I began to write cdist:
+  * Type and core cleanly seperated
-
+  * Small codebase in core
- * Speed
- * Elegant code
- * Clean design
  * Good documentation (man pages)
- * Meaningful error messages
- * The no surprise factor
  * Consistency in behaviour, naming and documentation
+ * Meaningful error messages
+  * Either standard error messages from tools or added description for clearification
+ * The no surprise factor
+  * No magic guessing of what the user wants
+ * Simple and well-known DSL
+  * Posix shell
  * Easy integration into bare metal installations
- * Simple and well-known DSL: posix shell
+  * requires only ssh + sh
- * It must be very easy to extend and debug cdist
+ * Easy upgrade
- * Focus on reuse of existing functionality (like sh, ssh, find, rm, ...)
+  * ***There is no need to update cdist on target hosts!***
- * Easy upgrade: ***There is no need to update cdist on target hosts!***
+  * cdist only needs to be updated on the master server(s)
-  * cdist only needs to be update on the master server
+ * Very easy to extend
+  * Can be done via types, which can be stacked on top of others
+ * Reuse of existing functionality
+  * sh, ssh, find, rm, mv, ...
+ * Very easy to debug
+  * Just add set -x in the scripts

+NAME

+cdist-type__process - Start or stop process
+
+
+DESCRIPTION
+-----------
+This cdist type allows you to define the state of a process.
+
+
+REQUIRED PARAMETERS
+-------------------
+state::
+   State of the process: Either stopped or running.
+
+
+OPTIONAL PARAMETERS
+-------------------
+name::
+   Process name to match on when using pgrep -f -x.
+
+stop::
+   Executable to use for stopping the process.
+
+start::
+   Executable to use for starting the process.
+
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+# Start /usr/sbin/sshd if not running
+__process /usr/sbin/sshd --state running
+
+# Start /usr/sbin/sshd if not running with a different binary
+__process /usr/sbin/sshd --state running --start "/etc/rc.d/sshd start"
+
+# Stop the process using kill (the type default)
+__process /usr/sbin/sshd --state stopped
+
+# Stop the process using /etc/rc.d/sshd stop
+__process /usr/sbin/sshd --state stopped --stop "/etc/rc.d/sshd stop"
+
+# Ensure cups is running, which runs with -C ...:

 Cache:
-   Assume you want to configure stuff one host ("monitor node"),

-   depending on the configuration of other hosts ("cluster nodes").
+   - export variable $__cache
+      -> for current host

-   For instance, the monitor host would like to know,

-   This requires the monitor node to be able to
+remove --preseed from package_apt and add debconf_set_selection or similar

-   ask for all hosts, because cdist does not

-
-   If cdist keeps ("caches") the configuration of every
-   node it configures, each new node can query the
-   cache for existing nodes that acquired the given
