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].

# This file is a shell script that caches the results of configure
# tests run on this system so they can be shared between configure
# scripts and configure runs.  It is not useful on other systems.
# If it contains results you don't want to keep, you may remove or edit it.
#
# By default, configure uses ./config.cache as the cache file,
# creating it if it does not exist already.  You can give configure
# the --cache-file=FILE option to use a different cache file; that is
# what configure does when it calls configure scripts in
# subdirectories, so they share the cache.
# Giving --cache-file=/dev/null disables caching, for debugging configure.
# config.status only pays attention to the cache file if you give it the
# --recheck option to rerun configure.

# So, don't put newlines in cache variables' values.
# Ultrix sh set writes to stderr and can't be redirected directly,
# and sets the high bit in the cache file unless we assign to the vars.
