+  newfunction(:validate_absolute_path, :doc => <<-'DOC') do |args|
+    Validate the string represents an absolute path in the filesystem.  This function works
+    for windows and unix style paths.
+
+    The following values will pass:
+
+        $my_path = 'C:/Program Files (x86)/Puppet Labs/Puppet'
+        validate_absolute_path($my_path)
+        $my_path2 = '/var/lib/puppet'
+        validate_absolute_path($my_path2)
+        $my_path3 = ['C:/Program Files (x86)/Puppet Labs/Puppet','C:/Program Files/Puppet Labs/Puppet']
+        validate_absolute_path($my_path3)
+        $my_path4 = ['/var/lib/puppet','/usr/share/puppet']
+        validate_absolute_path($my_path4)
+
+    The following values will fail, causing compilation to abort:
+
+        validate_absolute_path(true)
+        validate_absolute_path('../var/lib/puppet')
+        validate_absolute_path('var/lib/puppet')
