# Prepare a package to use libtool.
#
# -c, --copy            copy files rather than symlinking them
#     --debug           enable verbose shell tracing

# -f, --force           replace existing files
# -i, --install         copy missing auxiliary files
#     --ltdl[=DIR]      install libltdl sources [default: libltdl]
#     --no-warn         don't display warning messages
#     --nonrecursive    prepare ltdl for non-recursive make
# -q, --quiet           work silently
#     --recursive       prepare ltdl for recursive make
#     --subproject      prepare ltdl to configure and build independently

#     --version         print version information and exit
# -h, --help            print short or long help message
#
# The following space or comma delimited options can be passed to $progname

#
# You must `cd' to the top directory of your package before you run
