murgr81.tap is "Murgatroyds Revenge" for the ZX81, translated and
patched to run on the Spectrum.

It's not completely `native', as I didn't really want to pull the
Basic to pieces (e.g. all those PEEKs). So while some bits are a *lot*
faster than on the '81, other bits are a little faster but not much.

src.tar.gz contains the source for the patch etc., suitable for
building on Linux/Unix. You don't need it, it's just here for those
who like that sort of thing. :-)
