+The files in source/tables define the pervasive tables and instruction 
+format tables.
+
+pervasives:
+
+ pervasives.h{c}
+ ===============
+  Defines the pervasive tables for pervasive kinds, type skeletons
+  and constants. Note these files are automatically generated.
+
+ pervinit.h{c}
+ =============
+  Defines the initialization functions for pervasive tables: such functions
+  are necessary because the pervasive names in the system run-time have 
+  special encoding in the simulator (source/simulator/mcstring.h{c}) for
+  garbage collection as opposed to simply C strings. These names have to
+  be laid out on the system memory upon system initialization.
+
+ instructions.h{c}
+ =================
+  Defines instruction formats and instruction opcodes.
+  Note these files are automatically generated.
