# Usage: $progname [OPTION]... [MODE-ARG]...
#
# Provide generalized library-building support services.
#
#       --config             show all configuration variables
#       --debug              enable verbose shell tracing

#       --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

#       --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.

   - Space and tab are interpreted as delimiters. They are not treated as
     delimiters if they are surrounded by double quotes: "...".
   - Unescaped double quotes are removed from the input. Their only effect is
     that within double quotes, space and tab are treated like normal
     characters.
   - Backslashes not followed by double quotes are not special.
   - But 2*n+1 backslashes followed by a double quote become
     n backslashes followed by a double quote (n >= 0):
