the only use of this, i think, is for seeing the difference between 2
program ( hackers style ).

rem this is comp.bat, rename a file, run gxx, compare the 2 file
ren %2 %2.old
gxx %1 %2 %3
compare %2.old %2

--- How to call it  ( from a dos box, write )
comp -o newprog.exe newprog.cpp

--- What it does
ren newprog.exe newprog.exe.old
gxx -o newprog.exe newprog.cpp
compare newprog.exe.old newprog.exe

( Compare is a fictional program, it get 2 file and say where the difference
is )
This batch can work only if you use the form
gxx param outputFile inputFile && (param == -o )
else it do undefine beaviour, you can modify it like you want.
