+/* Set CONFIG_YABEL_DEBUG_FLAGS is a binary switch that allows you
+ * to select the following items to debug. 1=on 0=off. After you
+ * decide what you want to debug create the binary value, convert to hex
+ * and set the Option (Ex. CONFIG_YABEL_DEBUG_FLAGS = 0x31FF //Debug All).
+ *
+ * |-DEBUG_JMP - print info about JMP and RETF opcodes from x86emu
+ * ||-DEBUG_TRACE_X86EMU - print _all_ opcodes that are executed by x86emu (WARNING: this will produce a LOT of output)
+ * |||-Currently unused
+ * ||||-Currently unused
