-/* This parser handles all forms of promotion.
- * The parser resolves ambiguous moves by searching and check-testing.
- * It also parses comments of the form [anything] or (anything).
- *
- * [HGM] Parser extensively modified for bigger boards, Shogi-like syntax,
- * and unknow pieces. All pieces are now mandatory upper case, but can be
- * any letter A-Z. Files must be lower case (as before), but can run upto 'l'.
- * Ranks can be 0-9. The parser returns 0 for off-board files and ranks.
- * For an unknown piece (as mover or promotion piece) it returns
- * IllegalMove, like it does when the piece doesn't match.
- * Promotions can now also be appended Shogi-style, a bare '=' or '+',
- * and this is then returned as promotion character. The piece indicator
- * can be prefixed by a '+' to indicate it is a promoted piece.
