+ * PDD (platform description data) contains a set of system specific
+ * boot-parameters. Some of those parameters need to be handled
+ * special on updates, e.g. the MAC addresses. They must also be kept
+ * if the system is updated and one must be able to modify them when
+ * the system has booted the first time. This tool is intended to do
+ * PDD modification.
+ *
+ * 1.3 Removed argp because we want to use uClibc.
+ * 1.4 Minor cleanups
+ * 1.5 Migrated to new libubi
