#
# Prepare a package to use libtool.
#
# -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
# -i, --install         copy missing auxiliary files
#     --ltdl[=DIR]      install libltdl in a subdirectory [default: libltdl]
# -q, --quiet           work silently
# -v, --verbose         verbosely report processing
#     --version         print version information and exit
# -h, --help            print short or long help message
#
# You must `cd' to the top directory of your package before you run
# `$progname'.

# When reporting a bug, please describe a test case to reproduce it and
