+ ************************************************
+ 
+ Inst
+  - Joel Stanley's project.
+ 
+ SSAPRE
+  - Contains a project by Tanya Brethour that does loop invariant
+    code motion for traces.
+ 
+ Trigger
+  - Anand's OLD reoptimizer.
+ 
+ Mapping
+  - Functions to query the mapping between LLVM Instructions and MachineInstrs
+    which can be generated by opt and output as part of the SPARC
+    assembly by LLC. 
+ 
+ LightWtProfiling/Trigger
+  - Anand's redesigned reoptimizer.
+ 
+ TraceCache
+  - Manages traces for the reoptimizers.
+  - Classes TraceCache, VirtualMem, MemoryManager.
+  - Used by: Trigger, LightWtProfiling/Trigger, Inst/lib, BinInterface
+ 
+ ScratchMemory
+  - Contains two files with functions that have large blocks of for
+    loops. These for loops are overwritten by code which is written into
+    the trace cache.
+  - Used by: LightWtProfiling/Trigger, TraceCache/MemoryManager.cpp
+ 
+ BinInterface
+  - Analyze SPARC instructions, construct pseudo-SSA form, and manipulate
+    traces. Also includes a SPARC disassembler. Primarily done by
+    Cameron Buschardt.
+  - Used by: Trigger, SSAPRE/RuntimeLICM.cpp (only LLVMTrace),
+    Inst/lib/SparcInstManip.{cpp,h}
