Internal Program Version: cpio  2.15

GNU cpio is a program to manage archives of files. Cpio copies files
into or out of a cpio or tar archive. An archive is a file that contains
other files plus information about them, such as their pathname, owner,
time stamps, and access permissions. The archive can be another file on
the disk, a magnetic tape, or a pipe.
