  Pack is a simple version of the traditional Unix ar tool.
  It implements only the operations needed by Go.
  
  Usage:
  	go tool pack op file.a [name...]
  
  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
  valid archive file, which will be cleared before adding new entries. It
  is an error if the file exists but is not an archive.
  
  For the p, t, and x commands, listing no names on the command line
  causes the operation to apply to all files in the archive.
  
  In contrast to Unix ar, the r operation always appends to the archive,
  even if a file with the given name already exists in the archive. In this way
  pack's r operation is more like Unix ar's rq operation.
  
  Adding the letter v to an operation, as in pv or rv, enables verbose operation:
  For the c and r commands, names are printed as files are added.
  For the p command, each file is prefixed by the name on a line by itself.
  For the t command, the listing includes additional file metadata.
  For the x command, names are printed as files are extracted.
