Usage: $progname [OPTION]... [MODE-ARG]...

Provide generalized library-building support services.

-n, --dry-run         display commands without modifying any files
    --features        display configuration information and exit
    --finish          same as \`--mode=finish'
    --help            display this help message and exit

    --quiet           same as \`--silent'
    --silent          don't print informational messages
    --version         print version information

MODE must be one of the following:

      compile         compile a source file into a libtool object
      execute         automatically set library path, then run a program
      finish          complete the installation of libtool libraries
      install         install libraries or executables
      link            create a library or an executable
      uninstall       remove libraries from an installed directory

MODE-ARGS vary depending on the MODE.  Try \`$progname --help --mode=MODE' for
a more detailed description of MODE.
EOF
  ;;

compile)
  cat <<EOF
Usage: $progname [OPTION]... --mode=compile COMPILE-COMMAND... SOURCEFILE

Compile a source file into a libtool library object.

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'.
EOF
  ;;

execute)
  cat <<EOF
Usage: $progname [OPTION]... --mode=execute COMMAND [ARGS]...

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.
EOF
  ;;

finish)
  cat <<EOF
Usage: $progname [OPTION]... --mode=finish [LIBDIR]...

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.
EOF
  ;;

install)
  cat <<EOF
Usage: $progname [OPTION]... --mode=install INSTALL-COMMAND...

Install executables or libraries.

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

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

link)
  cat <<EOF
Usage: $progname [OPTION]... --mode=link LINK-COMMAND...

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
  -allow-undefined  allow a libtool library to reference undefined symbols
  -dlopen FILE      \`-dlpreopen' FILE if it cannot be dlopened at runtime
  -dlpreopen FILE   link in FILE and add its symbols to dld_preloaded_symbols
  -export-dynamic   allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
  -LLIBDIR          search LIBDIR for required installed libraries
  -lNAME            OUTPUT-FILE requires the installed library libNAME
  -o OUTPUT-FILE    create OUTPUT-FILE from the specified objects
  -rpath LIBDIR     the created library will eventually be installed in LIBDIR
  -static           do not do any dynamic linking of libtool libraries
  -version-info CURRENT[:REVISION[:AGE]]
                    specify library version info [each variable defaults to 0]

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.

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

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

uninstall)
  cat <<EOF
Usage: $progname [OPTION]... --mode=uninstall RM [RM-OPTION]... FILE...

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.
