+These are the comments as I received them from Albert Koelmans.
+The only thing I did was adapt the installation mechanism for ACK, and
+made some adaptions to de code generator to support the improved FP package.
+I also removed some comments that were no longer up-to-date.

+AMSTERDAM COMPILER KIT - BACKEND FOR ACORN RISC MACHINE PROCESSOR
+===========================================================================
+
+This file contains some advice on how to go about installing the ARM backend
+for the Amsterdam Compiler Kit (ACK), followed by a shar file containing the
+backend itself. In what follows, ~ will denote the ACK root directory (on
+most systems, this will be /usr/em), also called EMHOME in most makefiles.
+
+Make sure that your PATH includes ~/bin
+
+cd to ~/bin, and type 
+   ln ack arm
+
+cd to ~/mach/proto/ncg, and inspect file param.h. The constant MAXEMLINES
+should be at least 40. Edit the file if necessary.
+
+cd to ~/util/ncgg, and inspect file param.h. The constant MAXNODES should
+have as parameters at least 1500 and 1350. If this is not the case, edit the
+file and type 'make install' to generate a new ncgg.
+
+If some compilations fail, inspect file Out in the appropriate subdirectory
+to find the cause.
+
+ACK will create an a.out file which includes an ACK header and symbol table.
+Use the cv program to strip these off, after which the executable should be
+downloaded onto an Archimedes machine and have it's type set to FF8.
+
+Acknowledgements: the first version of the backend was written by an anonymous
+student at the Vrije Universiteit, Amsterdam. The code generator was further
+developed and debugged by Albert Koelmans. Andrew Michael wrote most of the
+assembler sources. A simple RiscOs interface was added by Albert Koelmans.
+All of this involved extensive help from Ceriel Jacobs. The assertion in the
+ACK documentation that writing a backend is a major task is certainly true...
+
+In case of major problems, bugs etc, contact me at the address below....
