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
    --debug           enable verbose shell tracing
-n, --dry-run         print commands rather than running them
-f, --force           replace existing files
    --help            display this message and exit
    --ltdl            install libltdl in a subdirectory
    --ltdl-tar        install the libltdl tarball
    --version         print version information and exit
