Some users want some sample application source from an old SGI cdrom for another project. The source is in an inst format file. I can't install it because (1) it would overrride the newer version and (2) the *software* on the cd is incompatible with this machine or IRIX version. I can get around (1) to some extent by using the -r option to inst, although it seems to open a can of worms about prerequisites, but inst provides no apparent way of getting around (2). Do any of you know how to win a fight with inst (I know it has the system's best interests at heart...) or how to unpack an inst format file or even a definition of inst format?
