For example, `$h #### `deprecation` -Prints deprecation warnings and logs a warning once for a given key. The uniqueness key - can appear once. The msg is the message text, including any positional information that is formatted by the user or caller of the method. The Puppet setting 'strict' affects this function. Set 'strict' to :error to output an error message, :off to output no message or error, or :warning (default) to output a warning. In Puppet versions lower than 4.0, you can set an environment variable to decide whether or not to log deprecation warnings (`ENV[STDLIB_LOG_DEPRECATION]`).
