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

       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 'libtool --help --mode=MODE' for a more detailed description of MODE.
