If you do not see a tag name associated with your programming language, then you are using a compiler that libtool does not support.

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.
