2) Copy the macs.0.2.tar.gz file to that new directory
3) Change to the new directory
4) Unpack the zipped file (tar -xvzf macs.0.2.tar.gz)
5) Type make
6) Change to root
6) Type make install (in the just created macs directory)
7) Check whether the program runs (./macs)
8) Check whether you have a man page for macs (man macs)
9) Have fun. (If the program is not running now you have a problem. I've not written something for troubleshooting :-( )
