This is a binary patching and incremental downloading tool, similar to rsync or zsync. It aims to improve the large binary download processes that previously were served by robocopy (i.e. full packages produced by the build farm).
The original code can be found in `//depot/usr/yuriy.odonnell/unsync`. This commit is a branch from the original location to preserve history.
While the codebase is designed to be self-contained and does not depend on any engine libraries, it mostly follows the UE coding guidelines and can be built with UBT.
Currently only Windows is supported, however the tool is expected to also work on Mac and Linux in the future.
