Puppet::Parser::Functions.newfunction(
  :binary_file,
  :type => :rvalue,
  :arity => 1,
  :doc => <<~DOC
    Loads a binary file from a module or file system and returns its contents as a Binary.

    The argument to this function should be a `<MODULE NAME>/<FILE>`
    reference, which will load `<FILE>` from a module's `files`
    directory. (For example, the reference `mysql/mysqltuner.pl` will load the
    file `<MODULES DIRECTORY>/mysql/files/mysqltuner.pl`.)

    This function also accepts an absolute file path that allows reading
    binary file content from anywhere on disk.

    An error is raised if the given file does not exists.

    To search for the existence of files, use the `find_file()` function.
