# Usage: $progname [OPTION]... [MODE-ARG]...
#
# Provide generalized library-building support services.
#
#     --config             show all configuration variables
#     --debug              enable verbose shell tracing
# -n, --dry-run            display commands without modifying any files
#     --features           display basic configuration information and exit
#     --mode=MODE          use operation mode MODE
#     --preserve-dup-deps  don't remove duplicate dependency libraries
#     --quiet, --silent    don't print informational messages
#     --tag=TAG            use configuration variables from tag TAG
# -v, --verbose            print informational messages (default)
#     --version            print version information
# -h, --help               print short or long help message
#
# MODE must be one of the following:
#
#       clean              remove files from the build directory
#       compile            compile a source file into a libtool object
#       execute            automatically set library path, then run a program
#       finish             complete the installation of libtool libraries
#       install            install libraries or executables
#       link               create a library or an executable
#       uninstall          remove libraries from an installed directory
#
# MODE-ARGS vary depending on the MODE.
# Try `$progname --help --mode=MODE' for a more detailed description of MODE.
