+For both options, FILE is a plain text file with user or group

+The @option{--owner} and @option{--group} options affect all files
+added to the archive.  @GNUTAR{} provides also two options that allow
+for more detailed control over owner translation:
+
+@table @option
+@item --owner-map=@var{file}
+Read UID translation map from @var{file}.
+
+When reading, empty lines are ignored.  The @samp{#} sign, unless
+quoted, introduces a comment, which extends to the end of the line.
+Each nonempty line defines mapping for a single UID.  It must consist
+of two fields separated by any amount of whitespace.  The first field
+defines original username and UID.  It can be a valid user name or
+a valid UID prefixed with a plus sign.  In both cases the
+corresponding UID or user name is inferred from the current host's
+user database.
+
+The second field defines the UID and username to map the original one
+to.  Its format can be the same as described above.  Otherwise, it can
+have the form @var{newname}:@var{newuid}, in which case neither
+@var{newname} nor @var{newuid} are required to be valid as per the
+user database.
+
+For example, consider the following file:
+
+@example
++10     bin
+smith   root:0
+@end example
+
+@noindent
+Given this file, each input file that is owner by UID 10 will be
+stored in archive with owner name @samp{bin} and owner UID
+corresponding to @samp{bin}.  Each file owned by user @samp{smith}
+will be stored with owner name @samp{root} and owner ID 0.  Other
+files will remain unchanged.
+
+When used together with @option{--owner-map}, the @option{--owner}
+option affects only files whose owner is not listed in the map file.
