Pack applies the operation to the archive, using the names as arguments to the operation.

The operation op is given by one of these letters:

	c	append files (from the file system) to a new archive
	p	print files from the archive
	r	append files (from the file system) to the archive
	t	list files from the archive
	x	extract files from the archive

The archive argument to the c command must be non-existent or a
