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

Generate a system-specific libtool script.

    --disable-shared       do not build shared libraries
    --help                 display this help and exit
    --no-verify            do not verify that HOST is a valid host type
    --quiet                same as \`--silent'
    --silent               don't 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

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

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