-"This utility allows re-naming several volumes in one go atomically.\n"
-"For example, if you have volumes A and B, then you may rename A into B\n"
-"and B into A at one go, and the operation will be atomic. This allows\n"
-"implementing atomic UBI volumes upgrades. E.g., if you have volume A\n"
-"and want to upgrade it atomically, you create a temporary volume B,\n"
-"put your new data to B, then rename A to B and B to A, and then you\n"
-"may remove old volume B.\n"
-"It is also allowed to re-name multiple volumes at a time, but 16 max.\n"
-"renames at once, which means you may specify up to 32 volume names.\n"
-"If you have volumes A and B, and re-name A to B, bud do not re-name\n"
-"B to something else in the same request, old volume B will be removed\n"
