1.1     23/01/94   o Added ambiguous move detection during import.
                   o Stopped the removal of hyphen characters from
                     player names during import.
                   o Added name-processing to conform to PGN standard.

1.2     24/01/94   o Added -I flag.
        27/01/94   o Added check for illegal moves due to "discovered
                     check".

1.3     01/02/94   o Compliance with PGN specification 1994.01.30:
                     1) Support for Numeric Annotation Glyphs (NAGs).
                     2) Add space between move number and move.
                     3) Output "SetUp" tag-pair for partial positions.
        03/02/94   o Added export format specifier "pgn_no_nag".
        08/02/94   o Documented compliance with PGN specification
                     1994.02.06.

1.3a    03/03/94   o Fixed conversion of escaped backslash (\\) back
                     into single backslash (as with escaped double
                     quote).

1.3b    09/04/94   o Added conversion of '_' to '-' when exporting to
                     PGN, and '-' to '_' when importing.

1.3c    30/04/94   o Added tidying of string (removing multiple/trailing
                     spaces) for Event, Site, White, Black and Annotator
                     tag-pairs during importing.
                   o Removed the need to have a single dot after the
                     White move number.

1.3d    18/08/94   o Fixed bug when importing unfinished game ("*");
                     the result used to be set to "1-0", rather than "=".

1.3e    14/09/94   o Added code to enforce 180-move limit.

1.3f	21/09/94   o Added -E option to allow 180-move limit not to be
                     enforced (Atari-ChessBase can apparently handle
                     games with 180-moves or move)

1.4     29/11/94   o Added -d option for diagram exporting.
                   o Added range-checking when importing from PGN format
                     (previously documented but not implemented!).
                   o Allowed round numbers to be in "(m/XXX)" or "[XXX]"
                     format.
        26/02/95   o Fixed bug when exporting "initial comment" for
                     games with no moves.
                   o Added Diagram creation code.
                   o Added -L option to allow PGN importing to start on a
                     specific line, and added PGN game-start line number
                     reporting.

1.5     22/08/95   o Added -l option to support long, unformatted
                     annotations as supported by ChessBase-for-Windows.
                   o Added -F option so that error messages can be
                     redirected to a file for later inspection.
                   o Added -k option to ignore ChessBase game checksum
                     errors.
                   o Changed line number related variables from 16-bit
                     to 32-bit as some PGN files are getting very large!
                   o Increased size of the move and comment buffer for
                     long, highly analysed games.
                   o Added support for PlyCount tag-pair and "$#" and "$N"
                     NAGs (even though the NAGs are illegal). These are
                     output by ChessBase-for-Windows 1.1, but CBASCII just
                     ignores them. Added support for LongECO tag-pair,
                     which isn't a valid PGN tag-pair but some rogue
                     conversion program is using it somewhere and people
                     are screaming because CBASCII is choking on it.

1.5a    24/08/95   o Fixed export problem with spaces exist either side of
                     hyphen in the players field; additional dots are
                     added.

1.6     19/10/95   o Added support for "short" pawn capture (and promotion)
                     notation (e.g "13. ef" and "39... ef=Q").
        31/03/96   o Discarded "empty" comments (those containing just
                     whitespace) during import (Chess Assistant 1.4 sometimes
                     produces PGN files with empty comments at the end of
                     games).
