"""A glorified dictionary of game headers as used in PGNs.
:param game:
Defaults to `None`. If bound to a game, any value set for
`"PlyCount"` is ignored and instead the real ply count of the
game is the value.
Aditionally the `"FEN"` header can not be modified if the game
already contains a move.
These headers are required by the PGN standard and can not be
removed:
`"Event`":
The name of the tournament or match event. Default is `"?"`.
`"Site`":
The location of the event. Default is `"?"`.
`"Date`":
The starting date of the game. Defaults to `"????.??.??"`. Must
be a valid date of the form YYYY.MM.DD. `"??"` can be used as a
placeholder for unknown month or day. `"????"` can be used as a
placeholder for an unknown year.
`"Round`":
The playing round ordinal of the game within the event. Must be
digits only or `"?"`. Defaults to `"?"`.
`"White`":
The player of the white pieces. Defaults to `"?"`.
`"Black`":
The player of the black pieces. Defaults to `"?"`.
`"Result`":
Defaults to `"*"`. Other values are `"1-0"` (white won),
`"0-1"` (black won) and `"1/2-1/2"` (drawn).
These additional headers are known:
`"Annotator"`:
The person providing notes to the game.
`"PlyCount"`:
The total moves played. Must be digits only. If a `game`
parameter is given any value set will be ignored and the real
ply count of the game will be used as the value.
`"TimeControl"`:
For example `"40/7200:3600"` (moves per seconds : sudden death
seconds). Validated to be of this form.
`"Time"`:
Time the game started as a valid HH:MM:SS string.
`"Termination"`:
Can be one of `"abandoned"`, `"adjudication"`, `"death"`,
`"emergency"`, `"normal"`, `"rules infraction"`,
`"time forfeit"` or `"unterminated"`.
`"Mode"`:
Can be `"OTB"` (over-the-board) or `"ICS"` (Internet chess
server).
`"FEN"`:
The initial position if the board as a FEN. If a game parameter
was given and the game already contains moves, this header can
not be set. The header will be deleted when set to the standard
chess start FEN.
`"SetUp"`:
Any value set is ignored. Instead the value is `"1"` is the
`"FEN"` header is set. Otherwise this header does not exist.
An arbitrary amount of other headers can be set. The capitalization
of the first occurence of a new header is used to normalize all
further occurences to it. Additional headers are not validated.
