+					   AMD64 POSTFIX CALCULATOR
+
+In an attempt to familiarise myself with AMD64 assembly I decided to
+write some little toy programs using it.  This is a simple postfix
+calculator for Linux (it does the system calls directly).  I've not
+attempted to handle any edge cases at all, so don't be suprised if it
+does weird stuff when fed invalid input.  I used the GNU assembler;
+there's a build script, build.sh, you can run to assemble and link the
+program.
