Usage: compile [--help] [--version] PROGRAM [ARGS]
Wrapper for compilers which do not understand

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'.
