// This file is used to Generate a new source Chajei Table File.
//
// it will read two files, one for Big5 and one for GB, to generate a new
// Chajei code table file.
//
// the two input files are sorted on the external keystroke pattern,(A1&A5)
// and both are complete Unicode files, ( there is 0xFEFF
// in its first two bytes),
//
// the two input files contain lots of lines,every line follows below format:
// XXXXXTCRL
// X: Key Code,
// T: Tab, 0x0009
// C: Unicode for this Character
// R: 0x000D
// L: 0x000A
//
// we will generate a new table source file, if the same pattern exists in both
// Big5 file and GB file, all those lines will be appended to the new file, and// the lines of Big5 will be written first, then GB Lines
//
// the new generated file must be sorted on the pattern.
