New in the compiler proper

• Completely new "make-world" system, properly documented (at last) in the installation guide. No Jmakefiles; but you *need* Gnu make (gmake). The more recent the better (v 3.70+).
• The "renamer" -- the part of the compiler that implements the Haskell module system -- has been completely rewritten, again. The format of interface files has changed significantly. Interface files generated by 2.01 will not work with 2.02.
• Even less special pleading for the Prelude than in 2.01. If you wanted to write your own Prelude and drop it in, you would have a really good chance now.
