-# Generate the file opcodes.h.
-#
-# This AWK script scans a concatenation of the parse.h output file from the
-# parser and the vdbe.c source file in order to generate the opcodes numbers
-# for all opcodes.  
-#
-# The lines of the vdbe.c that we are interested in are of the form:
-#
-#       case OP_aaaa:      /* same as TK_bbbbb */
-#
-# The TK_ comment is optional.  If it is present, then the value assigned to
-# the OP_ is the same as the TK_ value.  If missing, the OP_ value is assigned
-# a small integer that is different from every other OP_ value.
-#
-# We go to the trouble of making some OP_ values the same as TK_ values
-# as an optimization.  During parsing, things like expression operators
-# are coded with TK_ values such as TK_ADD, TK_DIVIDE, and so forth.  Later
-# during code generation, we need to generate corresponding opcodes like
-# OP_Add and OP_Divide.  By making TK_ADD==OP_Add and TK_DIVIDE==OP_Divide,
-# code to translate from one to the other is avoided.  This makes the
-# code generator run (infinitesimally) faster and more importantly it makes
-# the library footprint smaller.
-#
-# This script also scans for lines of the form:
-#
-#       case OP_aaaa:       /* jump, in1, in2, in3, out2-prerelease, out3 */
-#
-# When such comments are found on an opcode, it means that certain
-# properties apply to that opcode.  Set corresponding flags using the
-# OPFLG_INITIALIZER macro.
