     7  Pack is a simple version of the traditional Unix ar tool.
     8  It implements only the operations needed by Go.
     9  
    10  Usage:
    11  	go tool pack op file.a [name...]
    12  
    13  Pack applies the operation to the archive, using the names as arguments to the operation.
    14  
    15  The operation op is given by one of these letters:
    16  
    17  	c	append files (from the file system) to a new archive
    18  	p	print files from the archive
    19  	r	append files (from the file system) to the archive
    20  	t	list files from the archive
    21  	x	extract files from the archive
    22  
    23  The archive argument to the c command must be non-existent or a
    24  valid archive file, which will be cleared before adding new entries. It
    25  is an error if the file exists but is not an archive.
    26  
    27  For the p, t, and x commands, listing no names on the command line
    28  causes the operation to apply to all files in the archive.
    29  
    30  In contrast to Unix ar, the r operation always appends to the archive,
    31  even if a file with the given name already exists in the archive. In this way
    32  pack's r operation is more like Unix ar's rq operation.
    33  
    34  Adding the letter v to an operation, as in pv or rv, enables verbose operation:
    35  For the c and r commands, names are printed as files are added.
    36  For the p command, each file is prefixed by the name on a line by itself.
    37  For the t command, the listing includes additional file metadata.
    38  For the x command, names are printed as files are extracted.
