-  newfunction(:loadyaml, :type => :rvalue, :doc => <<-'ENDHEREDOC') do |args|
-    Load a YAML file containing an array, string, or hash, and return the data
-    in the corresponding native data type.
+    The first parameter can be a file path or a URL.
+    The second parameter is the default value. It will be returned if the file
+    was not found or could not be parsed.
 
-    For example:
+    @return [Array|String|Hash]
+      The data stored in the YAML file, the type depending on the type of data that was stored.
 
+    @example Example Usage:
         $myhash = loadyaml('/etc/puppet/data/myhash.yaml')
-    ENDHEREDOC
+        $myhash = loadyaml('https://example.local/my_hash.yaml')
