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'. | ||
