Deprecated parameters
---------------------
To deprecate type parameters one can declare a newline separated file
**parameter/deprecated** where each line contains deprecated parameter.
When it is used cdist writes warning line, e.g.:
To deprecate type parameters one can declare a file for each deprecated
parameter under **parameter/deprecated** directory.
When such parameter is used cdist writes warning line with deprecation message.
If such file has content then this content is printed as deprecation message.
If there is no content then generic parameter deprecation message is printed.
Example:
.. code-block:: sh
$ cat parameter/optional_multiple
foo
spam
eggs
$ cat parameter/deprecated
spam
eggs
$ echo '__foo foo --foo foo --spam spam' | ./bin/cdist config -i - 185.203.112.26
