# 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.
