# 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

#       --no-quiet, --no-silent

#                            print informational messages (default)

#       --no-warn            don't display warning messages

#       --tag=TAG            use configuration variables from tag TAG

#   -v, --verbose            print more informational messages than default

#       --no-verbose         don't print the extra informational messages

#       --version            print version information

#   -h, --help, --help-all   print short, long, or detailed 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.  When passed as first option,

# `--mode=MODE' may be abbreviated as `MODE' or a unique abbreviation of that.

# Try `$progname --help --mode=MODE' for a more detailed description of MODE.
