+# YScheme - an experimental compiler for Scheme
+
+
+This is the final submission for a compiler course I took from <a
+href="http://en.wikipedia.org/wiki/R._Kent_Dybvig">Kent Dybvig</a> at Indiana
+University. The compiler compiles a significant subset of Scheme into X64
+assembly and then linked with a runtime system written in C. I made attempts to
+simplify and innovate the compiler, so it is quite different from Kent's
+original design.
+
+In Kent's words, I put myself into trouble each week by doing things differently
+and then get myself out of it. Sometimes I did better than his compiler,
+sometimes, worse. But eventually I passed all his tests and got an A+.
+
+A notable thing of this compiler is its use of _high-order evaluation contexts_,
+which resulted sometimes in much simpler and shorter code, which is not
+necessarily ease to understand by people who haven't written CPS transformers.
