       Description of compile mode:

       Compile a source file into a libtool library object.

       This mode accepts the following additional options:

       -o OUTPUT-FILE
	      set the output file name to OUTPUT-FILE

       -no-suppress
	      do not suppress compiler output for multiple passes

       -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 exe-
       cutable 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
	      allow symbols from OUTPUT-FILE to be resolved with dlsym(3)

       -export-symbols SYMFILE
	      try to export only the symbols listed in SYMFILE

       -export-symbols-regex REGEX
	      try to export only the symbols matching REGEX

       -LLIBDIR
	      search LIBDIR for required installed libraries

       -lNAME OUTPUT-FILE requires the installed library libNAME

       -module
	      build a library that can dlopened

       -no-fast-install
	      disable the fast-install mode

       -no-install
	      link a not-installable executable

       -no-undefined
	      declare that a library does not refer to external symbols

       -o OUTPUT-FILE
	      create OUTPUT-FILE from the specified objects

       -objectlist FILE
	      Use a list of object files found in FILE to specify objects

       -precious-files-regex REGEX
	      don't remove output files matching REGEX

       -release RELEASE
	      specify package release information

       -rpath LIBDIR
	      the created library will eventually be installed in LIBDIR

       -R[ ]LIBDIR
	      add LIBDIR to the runtime path of programs and libraries

       -shared
	      only do dynamic linking of libtool libraries

       -shrext SUFFIX
	      override the standard shared library file extension

       -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 unin-
       stalled 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  conve-
       nience 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-compati-
       ble 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.
