+This is version 0.20 of the Glorious Glasgow Haskell compilation
+system (GHC).
+
+Version 0.20 is an "internal" release, intended *ONLY* for the most
+fanatical GHC hackers.
+
+* Many things about it may be broken, though it
+does compile and run most programs.
+
+* I/O and ccall scheme re-done; any such low-level code probably needs
+ fixing; I/O attempts to follow 1.3 I/O proposal. All ccall
+ arguments and results are automagically "boxed".
+
+* PrimOps fiddled; any code that uses them directly will probably need
+ attention.
+
+* We've renamed some things, so as to move to a we-don't-steal-user-
+ name-space policy. Thus "tagCmp" has become "_tagCmp". Names starting
+ with underscores are now cool if -fglasgow-exts.
+
+ You might want to see our "state-interface" document if you mess
+ with all this low-level/non-standard stuff; I'll try to remember to
+ put a copy up for FTP.
+
+* No promises about profiling.
+
+* Documentation is untouched since 0.19.
+
+Version 0.19 was the last public release. It has held up pretty well
+and should be available wherever you got 0.20 from. I commend 0.19 to
+all sane people.
+
+Configuring 0.20 is a little different than 0.19:
+
+ % cd <very-top>
+ % ./configure --with-boot=c
+ % ./STARTUP-ghc std
+ % cd ghc; make
+
+Things to note:
+
+* It's wrong for jmake to tell you "0: unknown flag -traditional"; but
+ it is harmless.
+
+* The 0.20 compiler seems more likely to run out of stack; use
+ -Rmax-stksize2m (or something) to increase; within the distribution,
+ probably something like...
+
+ % make EXTRA_HC_OPTS="-H20m -Rmax-stksize4m"
+
+See the "configure" script if you want to know what other options are
+-- there is no other documentation at this time!
