      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
  ;;

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:

  -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 or shared library creation
  -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' or \`.l_o' files) may be specified, and the \`-rpath'
option 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.
