+ (description "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:
+@table @command
+@item unzck
+To decompress a zchunk file.
+@item zck
+To compress a new zchunk file, or re-compress an existing one.
+@item zck_delta_size
+To calculate the difference between two zchunk files.
+@item zck_gen_zdict
+To create a dictionary for a zchunk file.
+@item zck_read_header
+To read a zchunk header.
+@item zckdl
+To download a zchunk file.
+@end table")
