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'.
