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