 # This AWK script scans the opcodes.h file (which is itself generated by
 # another awk script) and uses the information gleaned to create the
 # opcodes.c source file.
 #
 # Opcodes.c contains strings which are the symbolic names for the various
 # opcodes used by the VDBE.  These strings are used when disassembling a
 # VDBE program during tracing or as a result of the EXPLAIN keyword.
