A file format designed for highly efficient deltas while maintaining good compression
Description
zchunk is a compressed file format that splits the file into independent
chunks. This allows you to only download changed chunks when downloading a new
version of the file, and also makes zchunk files efficient over rsync.
zchunk files are protected with strong checksums to verify that the file you
downloaded is, in fact, the file you wanted.
As of zchunk-1.0, the ABI and API have been marked stable, and the only
changes allowed are backwards-compatible additions.
