+@cindex archives
+@cindex collections of files
+@smallexample
+ ar [-]@var{p}@var{mod} [ @var{membername} ] @var{archive} @var{files}@dots{}
+@end smallexample
+
+The GNU @code{ar} program creates, modifies, and extracts from
+archives. An @dfn{archive} is a single file holding a collection of
+other files in a structure that makes it possible to retrieve
+the original individual files (called @dfn{members} of the archive).
+
+The original files' contents, mode (permissions), timestamp, owner, and
+group are preserved in the archive, and may be reconstituted on
+extraction.
+
+@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 modifier @samp{s}.
+Once created, this index is updated in the archive whenever @code{ar}
+makes a change to its contents (save for the @samp{q} update operation).
+An archive with such an index speeds up linking to the library, and
+allows routines in the library to call each other without regard to
+their placement in the archive.
+
+You may use @samp{nm -s} or @samp{nm +print-armap} to list this index
+table. If an archive lacks the table, another form of @code{ar} called
+@code{ranlib} can be used to add just the table.
+
+@code{ar} insists on at least two arguments to execute: one
+keyletter specifying the @emph{operation} (optionally accompanied by other
+keyletters specifying @emph{modifiers}), and the archive name to act on.
+
+Most operations can also accept further @var{files} arguments,
+specifying particular files to operate on.
+
+GNU @code{ar} allows you to mix the operation code @var{p} and modifier
+flags @var{mod} in any order, within the first command-line argument.
+
+If you wish, you may begin the first command-line argument with a
+dash.
+
+@cindex operations on archive
+The @var{p} keyletter specifies what operation to execute; it may be
+any of the following, but you must specify only one of them:
+
+@table @code
+@item d
+@cindex deleting from archive
+@emph{Delete} modules from the archive. Specify the names of modules to
+be deleted as @var{files}; the archive is untouched if you
+specify no files to delete.
+
+If you specify the @samp{v} modifier, @code{ar} will list each module
+as it is deleted.
+
+@item m
+@cindex moving in archive
+Use this operation to @emph{move} members in an archive.
+
+The ordering of members in an archive can make a difference in how
+programs are linked using the library, if a symbol is defined in more
+than one member.
+
+If no modifiers are used with @code{m}, any members you name in the
+@var{files} arguments are moved to the @emph{end} of the archive;
+you can use the @samp{a}, @samp{b}, or @samp{i} modifiers to move them to a
+specified place instead.
+
+@item p
+@cindex printing from archive
+@emph{Print} the specified members of the archive, to the standard
+output file. If the @samp{v} modifier is specified, show the member
+name before copying its contents to standard output.
+
+If you specify no @var{files}, all the files in the archive are printed.
+
+@item q
+@cindex quick append to archive
+@emph{Quick append}; add @var{files} to the end of @var{archive},
+without checking for replacement.
+
+The modifiers @samp{a}, @samp{b}, and @samp{i} do @emph{not} affect this
+operation; new members are always placed at the end of the archive.
+
+The modifier @samp{v} makes @code{ar} list each file as it is appended.
+
+Since the point of this operation is speed, the archive's symbol table
+index is not updated, even if it already existed; you can use @samp{ar s} or
+@code{ranlib} explicitly to update the symbol table index.
+
+@item r
+@cindex replacement in archive
+Insert @var{files} into @var{archive} (with @emph{replacement}). This
+operation differs from @samp{q} in that any previously existing members
+are deleted if their names match those being added.
+
+If one of the files named in @var{files} doesn't exist, @code{ar}
+displays an error message, and leaves undisturbed any existing members
+of the archive matching that name.
+
+By default, new members are added at the end of the file; but you may
+use one of the modifiers @samp{a}, @samp{b}, or @samp{i} to request
+placement relative to some existing member.
+
+The modifier @samp{v} used with this operation elicits a line of
+output for each file inserted, along with one of the letters @samp{a} or
+@samp{r} to indicate whether the file was appended (no old member
+deleted) or replaced.
+
+@item t
+@cindex contents of archive
+Display a @emph{table} listing the contents of @var{archive}, or those
+of the files listed in @var{files} that are present in the
+archive. Normally only the member name is shown; if you also want to
+see the modes (permissions), timestamp, owner, group, and size, you can
+request that by also specifying the @samp{v} modifier.
+
+If you do not specify any @var{files}, all files in the archive
+are listed.
+
+@cindex repeated names in archive
+@cindex name duplication in archive
+If there is more than one file with the same name (say, @samp{fie}) in
+an archive (say @samp{b.a}), @samp{ar t b.a fie} will list only the
+first instance; to see them all, you must ask for a complete
+listing---in our example, @samp{ar t b.a}.
+@c WRS only; per Gumby, this is implementation-dependent, and in a more
+@c recent case in fact works the other way.
+
+@item x
+@cindex extract from archive
+@emph{Extract} members (named @var{files}) from the archive. You can
+use the @samp{v} modifier with this operation, to request that
+@code{ar} list each name as it extracts it.
+
+If you do not specify any @var{files}, all files in the archive
+are extracted.
+
+@end table
+
+A number of modifiers (@var{mod}) may immediately follow the @var{p}
+keyletter, to specify variations on an operation's behavior:
+
+@table @code
+@item a
+@cindex relative placement in archive
+Add new files @emph{after} an existing member of the
+archive. If you use the modifier @code{a}, the name of an existing archive
+member must be present as the @var{membername} argument, before the
+@var{archive} specification.
+
+@item b
+Add new files @emph{before} an existing member of the
+archive. If you use the modifier @code{b}, the name of an existing archive
+member must be present as the @var{membername} argument, before the
+@var{archive} specification. (same as @samp{i}).
+
+@item c
+@cindex creating archives
+@emph{Create} the archive. The specified @var{archive} is always
+created if it didn't exist, when you request an update. But a warning is
+issued unless you specify in advance that you expect to create it, by
+using this modifier.
+
+@item i
+Insert new files @emph{before} an existing member of the
+archive. If you use the modifier @code{i}, the name of an existing archive
+member must be present as the @var{membername} argument, before the
+@var{archive} specification. (same as @samp{b}).
+
+@item l
+This modifier is accepted but not used.
+@c whaffor ar l modifier??? presumably compat; with
+@c what???---pesch@@cygnus.com, 25jan91
+
+@item o
+@cindex dates in archive
+Preserve the @emph{original} dates of members when extracting them. If
+you do not specify this modifier, files extracted from the archive
+will be stamped with the time of extraction.
+
+@item s
+@cindex writing archive index
+Write an object-file index into the archive, or update an existing one,
+even if no other change is made to the archive. You may use this modifier
+flag either with any operation, or alone. Running @samp{ar s} on an
+archive is equivalent to running @samp{ranlib} on it.
+
+@item u
+@cindex updating an archive
+Normally, @code{ar r}@dots{} inserts all files
+listed into the archive. If you would like to insert @emph{only} those
+of the files you list that are newer than existing members of the same
+names, use this modifier. The @samp{u} modifier is allowed only for the
+operation @samp{r} (replace). In particular, the combination @samp{qu} is
+not allowed, since checking the timestamps would lose any speed
+advantage from the operation @samp{q}.
+
+@item v
+This modifier requests the @emph{verbose} version of an operation. Many
+operations display additional information, such as filenames processed,
+when the modifier @samp{v} is appended.

+@c Bonus for doc-source readers: you can also say +format=strange (or
