-PyPy JIT part 1
-==========================
+JIT Part 1: high level, language dependent
 
 - generated as translation aspect from PyPy Interpreter
 - stays in sync with the evolution of the language
+- separation of concerns
 - same technique works for other languages
 
-PyPy JIT part 2
-=========================
+Recipe for a JIT (2)
+==========================
+
+JIT Part 2: platform-specific code generation and optimizations
 
 - no cross-platform code generation toolkit
 - needs to be manually rewritten for each platform
 - orthogonal to the source language
 - can reuse existing code generation and optimization projects
 
-Conclusion
+Summary
+=========================
+
+- don't port new languages to new platforms manually
+- manually port general translation toolsuites
+- start from high-level Language Definitions
+- regenerate Interpreters automatically
+- get Just-In-Time Compilers for free :-)
