- * 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
