Usage: $progname [OPTION]...

Prepare a package to use libtool.

    --automake        work silently, and assume that Automake is in use
-c, --copy            copy files rather than symlinking them
-f, --force           replace existing files
    --help            display this message and exit
    --version         print version information and exit

You must \`cd' to the top directory of your package before you run
\`$progname'.
