+================
+The Architecture
+================
+
+Polly is a loop optimizer for LLVM. Starting from LLVM-IR it detects and
+extracts interesting loop kernels. For each kernel a mathematical model is
+derived which precisely describes the individual computations and memory
+accesses in the kernels. Within Polly a variety of analysis and code
+transformations are performed on this mathematical model. After all
+optimizations have been derived and applied, optimized LLVM-IR is regenerated
+and inserted into the LLVM-IR module.
