zchunk 1.5.1

Compressed file format for efficient deltas

The zchunk compressed file format allows splitting a file into independent chunks. This makes it possible to retrieve only changed chunks when downloading a new version of the file, and also makes zchunk files efficient over rsync. Along with the library, this package provides the following utilities:

unzck: To decompress a zchunk file.
zck: To compress a new zchunk file, or re-compress an existing one.
zck_delta_size: To calculate the difference between two zchunk files.
zck_gen_zdict: To create a dictionary for a zchunk file.
zck_read_header: To read a zchunk header.
zckdl: To download a zchunk file.
