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

Generate a system-specific libtool script.

    --build                configure for building on BUILD [BUILD=HOST]

    --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

    --add-tag=TAG          append an alternate configuration

    --with-gcc             assume that the GNU C compiler will be used

    --with-gnu-ld          assume that the C compiler uses the GNU linker

    --prefer-pic           try to use only PIC objects

    --prefer-non-pic       try to use only non-PIC objects

    --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].
