+%description
+zchunk is a compressed file format that splits the file into independent
+chunks.  This allows you to only download the differences 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.
