 built.  A good place to start reading the compiler is
 "base/toplev.scm" which is the top-level driver of the program.
 
-"fggen" contains the Flow Graph (FG) generator.  This converts SCode
-to the internal FG format which is used in the front end of the
-compiler.
-
-"fgopt" contains a number of passes that analyze and optimize the FG
-intermediate representation.  Most of the Scheme-specific technology
-is here.
+"midend" contains the higher level transformations, based on an
+s-expression syntax called KMP-Scheme.  Complex operations are
+transformed into simpler operations in a sequence Textual
+transformations.  The oder of the transformations is specified in
+"midend/midend.scm".  The first stage, "midend/inlate.scm", converts
+an SCode program into KMP-Scheme.  The last stage,
+"midend/rtlgen.scm", converts a limited subset of KMP-Scheme into RTL
+code.
 
 "rtlbase" contains the definition of the Register Transfer Language
 (RTL) data abstractions.  This is a second intermediate language which
 is a fairly standard intermediate representation for compilers.
 
-"rtlgen" contains the pass that converts the FG format to RTL.  This
-corresponds directly to what most compilers consider the "code
-generator".
-
 "rtlopt" contains several passes that analyze and optimize the RTL
 representation.  Such things as common subexpression elimination,
 lifetime analysis, dead code elimination, and register allocation and
