librsync implements the "rsync" algorithm, which allows remote
differencing of binary files. librsync computes a delta relative to a
file's checksum, so the two files need not both be present to generate
This library was previously known as libhsync up to version 0.9.0.
The current version of this package does not implement the rsync
network protocol and uses a delta format slightly more efficient than
and incompatible with rsync 2.4.6.
