--finish same as \`--mode=finish'
--help display this help message and exit
--mode=MODE use operation mode MODE [default=inferred from MODE-ARGS]

MODE must be one of the following:
compile compile a source file into a libtool object
dlname print filenames to use to \`dlopen' libtool libraries
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

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
;;
dlname)
cat <<EOF
Usage: $progname [OPTION]... --mode=dlname LTLIBRARY...
Print filenames to use to \`dlopen' libtool libraries.
Each LTLIBRARY is the name of a dynamically loadable libtool library (one that
was linked using the \`-export-dynamic' option).
The names to use are printed to standard output, one per line.
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:
-allow-undefined allow a libtool library to reference undefined 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 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' 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.
