I'm translating rsync.1, and i'm having some problems with the --compare-dest option description, actually i dont understand the part which describes the usefulness of this option, it says :
This is useful for doing transfers to a new destination while leaving existing files intact, and then doing a flash-cutover when all files have been successfully transferred (for example by moving directories around and removing the old directory, although this requires also doing the transfer with -I to avoid skipping files that havenīt changed). If someone could explain me this (especially the flash-cutover thing) , maybe with a little example, it would greatly help me for the translation. Thanks in advance Denis
