*******************************************************************************
* *
* "annotate" command is used to search through the game in a pgn file, and *
* provide a qualitative analysis of each move played and then creating a new *
* output file (xxx.can) containing the original game + new commentary. *
* *
* The normal output of this command is a file, in PGN format, that contains *
* the moves of the game, along with analysis when Crafty does not think that *
* move was the best choice. The definition of "best choice" is somewhat *
* vague, because if the move played is "close" to the best move available, *
* Crafty will not comment on the move. "Close" is defined by the <margin> *
* option explained below. This basic type of annotation works by first *
* using the normal tree search algorithm to find the best move. If this *
* move was the move played, no output is produced. If a different move is *
* considered best, then the actual move played is searched to the same depth *
* and if the best move and actual move scores are within <margin> of each *
* other, no comment is produced, otherwise Crafty inserts the evaluation for *
* the move played, followed by the eval and PV for the best continuation it *
* found. You can enter suggested moves for Crafty to analyze at any point *
* by simply entering a move as an analysis-type comment using (move) or *
* {move}. Crafty will search that move in addition to the move actually *
* played and the move it thinks is best. *
* *
* The format of the command is as follows: *
* *
* annotate filename b|w|bw|name moves margin time [n] *
* *
* Filename is the input file where Crafty will obtain the moves to annotate, *
* and output will be written to file "filename.can". *
* *
* annotateh filename b|w|bw|name moves margin time [n] *
* *
* Can be used to produce an HTML-compatible file that includes bitmapped *
* diagrams of the positions where Crafty provides analysis. This file can be*
* opened by a browser to provide much easier 'reading'. *
* *
* annotatet filename b|w|bw|name moves margin time [n] *
* *
* Can be used to produce a LaTeX-compatible file that includes LaTeX chess *
* fonts. This file can be read/printed by any program that can handle LaTeX *
* input. *
* *
* Where b/w/bw indicates whether to annotate only the white side (w), the *
* black side (b) or both (bw). You can also specify a name (or part of a *
* name, just be sure it is unique in the name tags for clarity in who you *
* mean). *
* *
* Moves indicates the move or moves to annotate. It can be a single move, *
* which indicates the starting move number to annotate, or it can be a range,*
* which indicates a range of move (1-999 gets the whole game.) *
* *
* Margin is the difference between Crafty's evaluation for the move actually *
* played and for the move Crafty thinks is best, before Crafty will generate *
* a comment in the annotation file. 1.0 is a pawn, and will only generate *
* comments if the move played is 1.000 (1 pawn) worse than the best move *
* found by doing a complete search. *
* *
* Time is time per move to search, in seconds. *
* *
* [n] is optional and tells Crafty to produce the PV/score for the "n" best *
* moves. Crafty stops when the best move reaches the move played in the game*
* or after displaying n moves, whichever comes first. If you use -n, then it*
* will display n moves regardless of where the game move ranks. *
