'--mode=MODE'.  For example, the following are equivalent:

          $ libtool --mode=execute --dry-run gdb prog.exe
          $ libtool        execute --dry-run gdb prog.exe
          $ libtool        exe     --dry-run gdb prog.exe
          $ libtool        e       --dry-run gdb prog.exe

     MODE must be set to one of the following:

     'compile'
          Compile a source file into a libtool object.

     'execute'
          Automatically set the library path so that another program can
          use uninstalled libtool-generated programs or libraries.

     'link'
          Create a library or an executable.

     'install'
          Install libraries or executables.

     'finish'
          Complete the installation of libtool libraries on the system.

     'uninstall'
          Delete installed libraries or executables.

     'clean'
          Delete uninstalled libraries or executables.

'--tag=TAG'
     Use configuration variables from tag TAG (*note Tags::).

'--preserve-dup-deps'
     Do not remove duplicate dependencies in libraries.  When building
     packages with static libraries, the libraries may depend circularly
     on each other (shared libs can too, but for those it doesn't
     matter), so there are situations, where -la -lb -la is required,
     and the second -la may not be stripped or the link will fail.  In
     cases where these duplications are required, this option will
     preserve them, only stripping the libraries that libtool knows it
     can safely.

'--quiet'
'--silent'
     Do not print out any progress or informational messages.

'-v'
'--verbose'
     Print out progress and informational messages (enabled by default),
     as well as additional messages not ordinary seen by default.

'--no-quiet'
'--no-silent'
     Print out the progress and informational messages that are seen by
     default.  This option has no effect on whether the additional
     messages seen in '--verbose' mode are shown.

'--no-verbose'
     Do not print out any additional informational messages beyond those
     ordinarily seen by default.  This option has no effect on whether
     the ordinary progress and informational messages enabled by
     '--no-quiet' are shown.

     Thus, there are now three different message levels (not counting
     '--debug'), depending on whether the normal messages and/or the
     additional verbose messages are displayed.  Note that there is no
     mechanism to display verbose messages, without also displaying
     normal messages.

     *default*
          Normal messages are displayed, verbose messages are not
          displayed.  In addition to being the default mode, it can be
          forcibly achieved by using both option '--no-verbose' and
          either option '--no-silent' or option '--no-quiet'.

     *silent*
          Neither normal messages nor verbose messages are displayed.
          This mode can be achieved using either option '--silent' or
          option '--quiet'.

     *verbose*
          Both normal messages and verbose messages are displayed.  This
          mode can be achieved using either option '-v' or option
          '--verbose'.

'--version'
     Print libtool version information and exit.

   The current 'libtool' implementation is done with a shell script that
needs to be invoked by the shell that 'configure' chose for configuring
'libtool' (*note The Autoconf Manual: (autoconf)config.status
Invocation.).  This shell is set in the she-bang ('#!') line of the
'libtool' script.  Using a different shell may cause undefined behavior.

   The MODE-ARGS are a variable number of arguments, depending on the
selected operation mode.  In general, each MODE-ARG is interpreted by
programs libtool invokes, rather than libtool itself.

* Menu:

* Compile mode::                Creating library object files.
* Link mode::                   Generating executables and libraries.
* Execute mode::                Debugging libtool-generated programs.
* Install mode::                Making libraries and executables public.
* Finish mode::                 Completing a library installation.
* Uninstall mode::              Removing installed executables and libraries.
* Clean mode::                  Removing uninstalled executables and libraries.
