+NAME

+cdist-type__key_value - Change property values in files
+
+
+DESCRIPTION
+-----------
+This cdist type allows you to change values in a key value based config
+file.
+
+

+-------------------
+value::
+   The value for the key. Setting the value to __NOTSET__ will remove the key
+   from the file.
+file::
+   The file to operate on.
+delimiter::
+   The delimiter which seperates the key from the value.
+
+
+OPTIONAL PARAMETERS
+-------------------
+key::
+   The key to change. Defaults to object_id.
+
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------------------------
+# Set the maximum system user id 
+__key_value SYS_UID_MAX --file /etc/login.defs --value 666 --delimiter ' '
+
+# Same with fancy id
+__key_value my-fancy-id --file /etc/login.defs --key SYS_UID_MAX --value 666 \
+   --delimiter ' '
+
+# Enable packet forwarding
+__key_value net.ipv4.ip_forward --file /etc/sysctl.conf --value 1 \
