Usage: $progname [OPTION]... LTMAIN [HOST]
Generate a system-specific libtool script.
--disable-shared do not build shared libraries
--disable-static do not build static libraries
--help display this help and exit
--no-verify do not verify that HOST is a valid host type
--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
LTMAIN is the \`ltmain.sh' shell script fragment that provides basic libtool
functionality.
HOST is the canonical host system name [default=guessed].
