+# Definition: datacat
+#
+# This definition allows you to declare datacat managed files.
+#
+# Parameters:
+# All parameters are as for the file type, with the addition of a $template

+# file.
+#
+# Sample Usage:
+#  datacat { '/etc/motd':
+#    owner => 'root',
+#    group => 'root,
+#    template => 'motd/motd.erb',
+#  }
