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