++Description: compress a file into independent chunks
++ zchunk is a compressed file format that splits the file into independent
++ chunks. This allows one 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
++ downloaded is, in fact, the file desired.
++ .
++ This package contains the command-line tools.
