+@cindex @code{ar} compatibility
+GNU @code{ar} is designed to be compatible with two different

+specify the single command-line option @samp{-M}, you can control it
+with a script supplied via standard input, like the MRI ``librarian''
+program.

+
+@cindex MRI compatibility, @code{ar}
+@cindex scripts, @code{ar}
+If you use the single command-line option @samp{-M} with @code{ar}, you
+can control its operation with a rudimentary command language. This
+form of @code{ar} operates interactively if standard input is coming
+directly from a terminal. During interactive use, @code{ar} prompts for
+input (the prompt is @samp{AR >}), and continues executing even after
+errors. If you redirect standard input to a script file, no prompts are
+issued, and @code{ar} abandons execution (with a nonzero exit code)
+on any error.
+
+The @code{ar} command language is @emph{not} designed to be equivalent
+to the command-line options; in fact, it provides somewhat less control
+over archives. The only purpose of the command language is to ease the
+transition to GNU @code{ar} for developers who already have scripts
+written for the MRI ``librarian'' program.
+
+The syntax for the @code{ar} command language is straightforward:
+@itemize @bullet
+@item
+commands are recognized in upper or lower case; for example, @code{LIST}
+is the same as @code{list}. In the following descriptions, commands are
+shown in upper case for clarity.
+
+@item
+a single command may appear on each line; it is the first word on the
+line.
+
+@item
+empty lines are allowed, and have no effect.
+
+@item
+comments are allowed; text after either of the characters @samp{*}
+or @samp{;} is ignored.
+
+@item
+Whenever you use a list of names as part of the argument to an @code{ar}
+command, you can separate the individual names with either commas or
+blanks. Commas are shown in the explanations below, for clarity.
+
+@item
+@samp{+} is used as a line continuation character; if @samp{+} appears
+at the end of a line, the text on the following line is considered part
+of the current command.
+@end itemize
+
+Here are the commands you can use in @code{ar} scripts, or when using
+@code{ar} interactively. Three of them have special significance:
+
+@code{OPEN} or @code{CREATE} specify a @dfn{current archive}, which is
+a temporary file required for most of the other commands.
+
+@code{SAVE} commits the changes so far specified by the script. Prior
+to @code{SAVE}, commands affect only the temporary copy of the current
+archive.
+
+@table @code
+@item ADDLIB @var{archive}
+@itemx ADDLIB @var{archive} (@var{module}, @var{module}, @dots{} @var{module})
+Add all the contents of @var{archive} (or, if specified, each named
+@var{module} from @var{archive}) to the current archive.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@item ADDMOD @var{file}, @var{file}, @dots{} @var{file}
+@c FIXME! w/Replacement?? If so, like "ar r @var{archive} @var{names}"
+@c else like "ar q..."
+Add each named @var{file} as a module in the current archive.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@item CLEAR
+Discard the contents of the current archive, cancelling the effect of
+any operations since the last @code{SAVE}. May be executed (with no
+effect) even if no current archive is specified.
+
+@item CREATE @var{archive}
+Creates an archive, and makes it the current archive (required for many
+other commands). The new archive is created with a temporary name; it
+is not actually saved as @var{archive} until you use @code{SAVE}.
+You can overwrite existing archives; similarly, the contents of any
+existing file named @var{archive} will not be destroyed until @code{SAVE}.
+
+@item DELETE @var{module}, @var{module}, @dots{} @var{module}
+Delete each listed @var{module} from the current archive; equivalent to
+@samp{ar -d @var{archive} @var{module} @dots{} @var{module}}.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@item DIRECTORY @var{archive} (@var{module}, @dots{} @var{module})
+@itemx DIRECTORY @var{archive} (@var{module}, @dots{} @var{module}) @var{outputfile}
+List each named @var{module} present in @var{archive}. The separate
+command @code{VERBOSE} specifies the form of the output: when verbose
+output is off, output is like that of @samp{ar -t @var{archive}
+@var{module}@dots{}}. When verbose output is on, the listing is like
+@samp{ar -tv @var{archive} @var{module}@dots{}}.
+
+Output normally goes to the standard output stream; however, if you
+specify @var{outputfile} as a final argument, @code{ar} directs the
+output to that file.
+
+@item END
+Exit from @code{ar}, with a @code{0} exit code to indicate successful
+completion. This command does not save the output file; if you have
+changed the current archive since the last @code{SAVE} command, those
+changes are lost.
+
+@item EXTRACT @var{module}, @var{module}, @dots{} @var{module}
+Extract each named @var{module} from the current archive, writing them
+into the current directory as separate files. Equivalent to @samp{ar -x
+@var{archive} @var{module}@dots{}}.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@ignore
+@c FIXME Tokens but no commands???
+@item FULLDIR
+
+@item HELP
+@end ignore
+
+@item LIST
+Display full contents of the current archive, in ``verbose'' style
+regardless of the state of @code{VERBOSE}. The effect is like @samp{ar
+tv @var{archive}}). (This single command is a GNU @code{ld}
+enhancement, rather than present for MRI compatibility.)
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@item OPEN @var{archive}
+Opens an existing archive for use as the current archive (required for
+many other commands). Any changes as the result of subsequent commands
+will not actually affect @var{archive} until you next use @code{SAVE}.
+
+@item REPLACE @var{module}, @var{module}, @dots{} @var{module}
+In the current archive, replace each existing @var{module} (named in
+the @code{REPLACE} arguments) from files in the current working directory.
+To execute this command without errors, both the file, and the module in
+the current archive, must exist.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
+
+@item VERBOSE
+Toggle an internal flag governing the output from @code{DIRECTORY}.
+When the flag is on, @code{DIRECTORY} output matches output from
+@samp{ar -tv @dots{}}.
+
+@item SAVE
+Commit your changes to the current archive, and actually save it as a
+file with the name specified in the last @code{CREATE} or @code{OPEN}
+command.
+
+Requires prior use of @code{OPEN} or @code{CREATE}.
