+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.
