+@cindex name length
+GNU @code{ar} can maintain archives whose members have names of any
+length; however, depending on how @code{ar} is configured on your
+system, a limit on member-name length may be imposed (for compatibility
+with archive formats maintained with other tools). If it exists, the
+limit is often 15 characters (typical of formats related to a.out) or 16
+characters (typical of formats related to coff).
+@cindex libraries
@code{ar} is considered a binary utility because archives of this sort
are most often used as @dfn{libraries} holding commonly needed
subroutines.
+@cindex symbol index
@code{ar} will create an index to the symbols defined in relocatable
-object modules in the archive when you specify the option @samp{s}.

-other without regard to their placement in the archive.

-@c instance, that it doesn't happen with 'q' updates elsewhere.

+@itemx +radix @var{number}
+@cindex size number format
+@cindex radix for section sizes
+Using one of these options, you can control whether the size of each
+section is given in decimal (@samp{-d}, or @samp{+radix 10}); octal
+(@samp{-o}, or @samp{+radix 8}); or hexadecimal (@samp{-x}, or
+@samp{+radix 16}). In @samp{+radix @var{number}}, only the three
+values (8, 10, 16) are supported. The total size is always given in two
+radices; decimal and hexadecimal for @samp{-d} or @samp{-x} output, or
+octal and hexadecimal if you're using @samp{-o}.
+
+@item +target @var{bfdname}
+@cindex object code format
+You can specify a particular object-code format for @var{objfiles} as
+@var{bfdname}. This may not be necessary; @var{size} can

@emph{WARNING:} @code{strip} modifies the files named in its argument,
rather than writing modified copies under different names.

@table @code
-@item -s | +strip-all
+@item -s
+@itemx +strip-all
+@cindex all symbols, discarding
This is the default case: strip all symbol entries from @var{objfiles}.
-@item -S | +strip-debug
+@item -g
+@itemx -S
+@itemx +strip-debug
+@cindex debugging symbols, discarding
Discard only debugging symbol information from @var{objfiles}.
-@item -x | +discard-all
+@item -x
+@itemx +discard-all
+@cindex local symbols, discarding
Discard all symbols local to each file in @var{objfiles}.
@emph{WARNING:} Note that @code{+discard-all} discards only @emph{local}
symbols, in spite of its name.
-@item -X | +discard-locals
+@item -X
+@itemx +discard-locals
Discard local symbols starting with @samp{L} from each file in
@var{objfiles}. (Some compilers produce internally-used symbols that
begin with @samp{L}.)
+
+@item -T @var{bfdname}
+@cindex object code format
+You can specify a particular object-code format @var{bfdname} for
+@var{objfiles}. This may not be necessary; @var{strip} can automatically
+recognize many formats. @xref{objdump}, for information on listing
+available formats.
