    39 Usage: compile [--help] [--version] PROGRAM [ARGS]
    41 Wrapper for compilers which do not understand `-c -o'.
    42 Remove `-o dest.o' from ARGS, run PROGRAM with the remaining
    43 arguments, and rename the output as expected.
    45 If you are trying to build a whole package this is not the
    46 right script to run: please start by reading the file `INSTALL'.
    48 Report bugs to <bug-automake@gnu.org>.
