-.Sh NAME
-.Nm tar
-.Nd The GNU version of the tar archiving utility
-.Sh SYNOPSIS
-$command_string
-.Op Ar options
-.Op Ar pathname ...
-.Sh DESCRIPTION
-.Nm Tar
-stores and extracts files from a tape or disk archive.
-.Pp
-The first argument to
-tar
-should be a function; either one of the letters
-.Cm $short_letters ,
-or one of the long function names.
-A function letter need not be prefixed with ``\\-'', and may be combined
-with other single-letter options.
-A long function name must be prefixed with
-.Cm \\\\-\\\\- .
-Some options take a parameter; with the single-letter form
-these must be given as separate arguments.
-With the long form, they may be given by appending
-.Cm = Ns Ar value
-to the option.
-.Sh FUNCTION LETTERS
-Main operation mode:
-$function_letters
-.Sh OTHER OPTIONS
-Operation modifiers:
-$option_letters
-.Sh ENVIRONMENT
-The behavior of tar is controlled by the following environment variables,
-among others:
-$env_variables
-.Sh EXAMPLES
-$examples
-.Sh SEE ALSO
-.\\" libarchive
-.Xr tar 5 ,
-.\\" man-pages
-.Xr symlink 7 ,
-.Xr rmt 8
-.Sh HISTORY
-The
-.Nm tar
-command appeared in
-.At v7 .
-.Sh BUGS
-The GNU folks, in general, abhor man pages, and create info documents instead.
-Unfortunately, the info document describing tar is licensed under the GFDL with
-invariant cover texts, which makes it impossible to include any text
-from that document in this man page.
-Most of the text in this document was automatically extracted from the usage
-text in the source.
-It may not completely describe all features of the program.
