Usage: $progname [OPTION]... [HOST [LTMAIN]]

Generate a system-specific libtool script.

    --debug                enable verbose shell tracing
    --disable-shared       do not build shared libraries
    --disable-static       do not build static libraries
    --disable-fast-install do not optimize for fast installation
    --enable-dlopen        enable dlopen support
    --enable-win32-dll     enable building dlls on win32 hosts
    --help                 display this help and exit
    --no-verify            do not verify that HOST is a valid host type
-o, --output=FILE          specify the output file [default=$default_ofile]
    --quiet                same as \`--silent'
    --silent               do not print informational messages
    --srcdir=DIR           find \`config.guess' in DIR
    --version              output version information and exit
    --with-gcc             assume that the GNU C compiler will be used
    --with-gnu-ld          assume that the C compiler uses the GNU linker
    --disable-lock         disable file locking
    --cache-file=FILE      configure cache file

LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
that provides basic libtool functionality.

HOST is the canonical host system name [default=guessed].
