+.Sh DESCRIPTION
+The
+.Nm
+command copies files to and from a
+.Nm
+archive.
+.Pp
+The following options are supported:
+.Bl -tag -width Fl
+.It Fl o
+Create an archive. Reads the list of files to store in the
+archive from standard input, and writes the archive on standard
+output.
+.Bl -tag -width Fl
+.It Fl a
+Reset the access times on files that has been copied to the
+archive.
+.It Fl A
+Append to the specified archive.
+.It Fl B
+Set block size of output to 5120 bytes.
+.It Fl c
+Use ASCII format for
+.Nm
+header for portability.
+.It Fl C Ar bytes
+Set the block size of output to
+.Ar bytes .
+.It Fl F Ar archive
+.It Fl O Ar archive
+Use the specified file name as the archive to write to.
+.It Fl H Ar format
+Write the archive in the specified format. Recognized
+formats are:
+.Bl -tag -width Ds
+.It Ar bcpio
+Old binary cpio format.
+.It Ar cpio
+Old octal character cpio format.
+.It Ar sv4cpio
+SVR4 hex cpio format.
+.It Ar tar
+Old tar format.
+.It Ar ustar
+POSIX ustar format.
+.El
+.It Fl L
+Follow symbolic links.
+.It Fl v
+Be verbose about operations. List filenames as they are
+written to the archive.
+.It Fl z
+Compress archive using
+.Xr gzip 1
+format.
+.It Fl Z
+Compress archive using
+.Xr compress 1
+format.
+.El
+.It Fl i
+Restore files from an archive. Reads the archive file from
+standard input and extracts files matching the
+.Ar patterns
+that were specified on the command line.
+.Bl -tag -width Fl
+.It Fl b
+Do byte- and word swapping after reading in data from the
+archive, for restoring archives created on systems with
+different byte order.
+.It Fl B
+Set the block size of the archive being read to 5120 bytes.
+.It Fl c
+Expect the archive headers to be in ASCII format.
+.It Fl C Ar bytes
+Read archive written with a blocksize of
+.Ar bytes .
+.It Fl d
+Create any intermediate directories as needed during
+restore.
+.It Fl E Ar file
+Read list of file name patters to extract or list from
+.Ar file .
+.It Fl f
+Restore all files except those matching the
+.Ar patterns
+given on the command line.
+.It Fl F Ar archive
+.It Fl I Ar archive
+Use the specified file as the input for the archive.
+.It Fl H Ar format
+Read an archive of the specified format. Recognized
+formats are:
+.Bl -tag -width Ds
+.It Ar bcpio
+Old binary cpio format.
+.It Ar cpio
+Old octal character cpio format.
+.It Ar sv4cpio
+SVR4 hex cpio format.
+.It Ar tar
+Old tar format.
+.It Ar ustar
+POSIX ustar format.
+.El
+.It Fl m
+Restore modification times on files.
+.It Fl r
+Rename restored files interactively.
+.It Fl s
+Swap bytes after reading data from the archive.
+.It Fl S
+Swap words after reading data from the archive.
+.It Fl t
+Only list the contents of the archive, no files or
+directories will be created.
+.It Fl u
+Overwrite files even when the file in the archive is
+older than the one that will be overwritten.
+.It Fl v
+Be verbose about operations. List filenames as they are
+copied in from the archive.
+.It Fl z
+Uncompress archive using
+.Xr gzip 1
+format.
+.It Fl Z
+Uncompress archive using
+.Xr compress 1
+format.
+.It Fl 6
+Process old-style \*Qcpio\*U format archives.
+.El
+.It Fl p
+Copy files from one location to another in a single pass.
+The list of files to copy are read from standard in and
+written out to a directory relative to the specified
+.Ar directory
+argument.
+.Bl -tag -width Fl
+.It Fl a
+Reset the access times on files that has been copied.
+.It Fl d
+Create any intermediate directories as needed to write
+the files at the new location.
+.It Fl l
+When possible, link files rather than creating an
+extra copy.
+.It Fl L
+Follow symbolic links.
+.It Fl m
+Restore modification times on files.
+.It Fl u
+Overwrite files even when the original file being copied is
+older than the one that will be overwritten.
+.It Fl v
+Be verbose about operations. List filenames as they are
+copied.
+.El
+.El
+.Sh ERRORS
+.Nm
+will exit with one of the following values:
+.Bl -tag -width 2n
+.It 0
+All files were processed successfully.
+.It 1
+An error occured.
+.El
+.Pp
+Whenever
+.Nm
+cannot create a file or a link when extracting an archive or cannot
+find a file while writing an archive, or cannot preserve the user
+ID, group ID, file mode or access and modification times when the
+.Fl p
+options is specified, a diagnostic message is written to standard
+error and a non-zero exit value will be returned, but processing
+will continue. In the case where
+.Nm
+cannot create a link to a file,
+.Nm
+will not create a second copy of the file.
+.Pp
+If the extraction of a file from an archive is prematurely terminated
+by a signal or error,
+.Nm
+may have only partially extracted the file the user wanted.
+Additionally, the file modes of extracted files and directories may
+have incorrect file bits, and the modification and access times may
+be wrong.
+.Pp
+If the creation of an archive is prematurely terminated by a signal
+or error,
+.Nm
+may have only partially created the archive which may violate the
+specific archive format specification.

+.Sh BUGS
+The
+.Fl d
+option is the default and cannot be turned off.
+The
+.Fl s
+and
+.Fl S
+options are currently not implemented.
