openrsync

Implementation of rsync with a BSD (ISC) license

This is an implementation of rsync with a BSD (ISC) license. It's compatible with a modern rsync (3.1.3 is used for testing, but any supporting protocol 27 will do), but accepts only a subset of rsync's command-line arguments. Its officially-supported operating system is OpenBSD, but it will compile and run on other UNIX systems. See Portability for details.
