syrep - 0.9-5 main

syrep is a generic file repository synchronization tool. It may be used to
synchronize large file hierarchies bidirectionally by exchanging patch files.
Syrep is truly peer-to-peer, no central servers are involved.
Synchronizations between more than two repositories are supported. The patch
files may be transferred via offline media, e.g. removable hard disks or
compact discs.
.
Files are tracked by their message digests, currently MD5. The following file
operations are tracked in the snapshot files: creation, deletion,
modification, creation of new hard or symbolic links, renaming. (The latter is
nothing more than a new hard link and removal of the old file). syrep doesn't
distinguish between soft and hard links. In fact even copies of files are
treated as the same. Currently, syrep doesn't synchronize file attributes like
access modes or modification times.
.
Syrep was written to facilitate the synchronization of two large digital music
repositories without direct network connection. Patch files of several
gigabytes are common in this situation.
.
Syrep is able to cope with 64 bit file sizes. (LFS)
.
Syrep is optimized for speed. It may make use of a message digest cache to
accelerate the calculation of digests of a whole directory hierarchy
