# with bootstrap, so set those here where they can still be over-
# ridden by the user, but otherwise take precedence.

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.
