newfunction(:hiera_hash, :type => :rvalue, :arity => -2, :doc =>
"Returns a merged hash of matches from throughout the hierarchy. In cases where two or
more hashes share keys, the hierarchy order determines which key/value pair will be
used in the returned hash, with the pair in the highest priority data source winning.
In addition to the required `key` argument, `hiera_hash` accepts two additional
arguments:
- a `default` argument in the second position, providing a hash to be returned in the
absence of any matches for the `key` argument
- an `override` argument in the third position, providing a data source to insert at
the top of the hierarchy, even if it would not ordinarily match during a Hiera data
source lookup. If Hiera doesn't find a match in the named override data source, it will
continue to search through the rest of the hierarchy.
`hiera_hash` expects that all values returned will be hashes. If any of the values
found in the data sources are strings or arrays, puppet will raise a type mismatch error.
More thorough examples of `hiera_hash` are available at:
<http://docs.puppetlabs.com/hiera/1/puppet.html#hiera-lookup-functions>
