      -prefer-pic
           try to build PIC objects only

      -prefer-non-pic
           try to build non-PIC objects only

      -shared
           do not build a `.o' file suitable for static linking

      -static
           only build a `.o' file suitable for static linking

      -Wc,FLAG
           pass FLAG directly to the compiler

      COMPILE-COMMAND is a command to be used in creating a `standard'
      object file from the given SOURCEFILE.

      The output file name is determined by removing the directory component
      from SOURCEFILE, then substituting the C source code suffix `.c' with
      the library object suffix, `.lo'.

      Description of link mode:

      Link object files or libraries together to form another library, or to
      create an executable program.

      LINK-COMMAND is a command using the C compiler that you would use to
      create a program from several object files.

      The following components of LINK-COMMAND are treated specially:

      -all-static
           do not do any dynamic linking at all

      -avoid-version
           do not add a version suffix if possible

      -bindir BINDIR
           specify path to binaries directory (for systems where libraries
           must be found in the PATH setting at runtime)

      -dlopen FILE
           `-dlpreopen' FILE if it cannot be dlopened at runtime

      -dlpreopen FILE
           link in FILE and add its symbols to lt_preloaded_symbols

      -export-dynamic

                                October 2011



      -static
           do not do any dynamic linking of uninstalled libtool libraries

      -static-libtool-libs
           do not do any dynamic linking of libtool libraries

      -version-info CURRENT[:REVISION[:AGE]]
           specify library version info [each variable defaults to 0]

      -weak LIBNAME
           declare that the target provides the LIBNAME interface

      -Wc,FLAG

      -Xcompiler FLAG
           pass linker-specific FLAG directly to the compiler

      -Wl,FLAG

      -Xlinker FLAG
           pass linker-specific FLAG directly to the linker

      -XCClinker FLAG
           pass link-specific FLAG to the compiler driver (CC)

      All other options (arguments beginning with `-') are ignored.

      Every other argument is treated as a filename.  Files ending in `.la'
      are treated as uninstalled libtool libraries, other files are standard
      or library object files.

      If the OUTPUT-FILE ends in `.la', then a libtool library is created,
      only library objects (`.lo' files) may be specified, and `-rpath' is
      required, except when creating a convenience library.

      If OUTPUT-FILE ends in `.a' or `.lib', then a standard library is
      created using `ar' and `ranlib', or on Windows using `lib'.

      If OUTPUT-FILE ends in `.lo' or `.o', then a reloadable object file is
      created, otherwise an executable program is created.

      Description of execute mode:

      Automatically set library path, then run a program.

      This mode accepts the following additional options:

      -dlopen FILE
           add the directory containing FILE to the library path

      This mode sets the library path environment variable according to
      `-dlopen' flags.

      If any of the ARGS are libtool executable wrappers, then they are
      translated into their corresponding uninstalled binary, and any of
      their required library directories are added to the library path.

      Then, COMMAND is executed, with ARGS as arguments.

      Description of install mode:

      Install executables or libraries.

      INSTALL-COMMAND is the installation command.  The first component
      should be either the `install' or `cp' program.

      The following components of INSTALL-COMMAND are treated specially:

      -inst-prefix-dir PREFIX-DIR
           Use PREFIX-DIR as a staging area for installation

      The rest of the components are interpreted as arguments to that
      command (only BSD-compatible install options are recognized).

      Description of finish mode:

      Complete the installation of libtool libraries.

      Each LIBDIR is a directory that contains libtool libraries.

      The commands that this mode executes may require superuser privileges.
      Use the `--dry-run' option if you just want to see what would be
      executed.

      Description of uninstall mode:

      Remove libraries from an installation directory.

      RM is the name of the program to use to delete files associated with
      each FILE (typically `/bin/rm').  RM-OPTIONS are options (such as
      `-f') to be passed to RM.

      If FILE is a libtool library, all the files associated with it are
      deleted.  Otherwise, only FILE itself is deleted using RM.

      Description of clean mode:

      Remove files from the build directory.

      RM is the name of the program to use to delete files associated with
      each FILE (typically `/bin/rm').  RM-OPTIONS are options (such as
      `-f') to be passed to RM.

      If FILE is a libtool library, object or program, all the files
      associated with it are deleted. Otherwise, only FILE itself is deleted
      using RM.
