+     "GNU Cpio copies files into or out of a cpio or tar archive. The
+archive can be another file on the disk, a magnetic tape, or a pipe.
+
+GNU Cpio supports the following archive formats: binary, old ASCII, new
+ASCII, crc, HPUX binary, HPUX old ASCII, old tar, and POSIX.1 tar. The
+tar format is provided for compatability with the tar program. By
+default, cpio creates binary format archives, for compatibility with
+older cpio programs. When extracting from archives, cpio automatically
+recognizes which kind of archive it is reading and can read archives
+created on machines with a different byte-order.")
