/*
* An utility to create UBI volumes.

+ * Author: Artem B. Bityutskiy <dedekind@linutronix.de>
+ * Frank Haverkamp <haver@vnet.ibm.com>
+ *
+ * 1.0 Initial release
+ * 1.1 Does not support erase blocks anymore. This is replaced by
+ * the number of bytes.
+ * 1.2 Reworked the user-interface to use argp.
+ * 1.3 Removed argp because we want to use uClibc.
+ * 1.4 Minor cleanups
+ * 1.5 Use a different libubi
