+This directory contains the necessary files to port the C compiler
+``LCC'' (available by FTP from sunsite.doc.ic.ac.uk in the directory
+/computing/programming/languages/c/lcc) to compile for Linux (a.out
+or ELF) by using NASM as a back-end code generator.
+
+This patch has been tested on lcc version 3.6.
+
+To install:
+
+- Copy `x86nasm.md' into the `src' directory of the lcc tree.
+
+- Copy either `lin-elf.c' or `lin-aout.c' into the `etc' directory.
+
+- If you're installing for a.out, edit `x86nasm.md' and change the
+  conditional after the comment reading "CHANGE THIS FOR a.out" in
+  the `defsymbol' function from `#if 0' to `#if 1'.
+
+- Make the following changes to `bind.c' in the `src' directory:
+
+  - Near the top of the file, add a line that reads
+	extern Interface x86nasmIR;
+
+  - In the `bindings' array, add the lines
+        "x86-nasm",      &x86nasmIR,
+        "x86/nasm",      &x86nasmIR,
+    (in sensible looking places...)
+
+  A sample `bind.c' has been provided to show what the result of
+  this might look like. You might be able to get away with using it
+  directly...
+
+- Modify the lcc makefile to include rules for x86nasm.o: this will
+  have to be done in about three places. Just copy any line with
+  `x86' on it and modify it to read `x86nasm' everywhere. (Except
+  that in the list of object files that rcc is made up from, do
+  remember to ensure that every line but the last has a trailing
+  backslash...)
+
+- You may have to modify the contents of `lin-elf.c' or `lin-aout.c'
+  to reflect the true locations of files such as crt0.o, crt1.o,
+  ld-linux.so and so forth. If you don't know where to find these,
+  compile a short C program with `gcc -v' and see what command line
+  gcc feeds to `ld'.
+
+- You should now be able to build lcc, using `lin-elf.c' or
+  `lin-aout.c' as the system-dependent part of the `lcc' wrapper
+  program.
+
+- Symlink x86nasm.c into the `src' directory before attempting the
+  triple test, or the compile will fail.
+
+- Now it should pass the triple test, on either ELF or a.out. Voila!
