Subject: Reuse the remoteglot library for a new book project.
X-Git-Url: https://git.sesse.net/?p=remoteglot-book;a=commitdiff_plain;h=2d13258e04f6800f1a5d29186a460994e442b4ff

Reuse the remoteglot library for a new book project.

Remove everything not related to the (new) book building.
It will keep on living in the remoteglot repository.

-<h2 style="clear: both;">Symbol explanation</h2>
-<ul>
-  <li><strong>Score:</strong> 1.00 is the value of one pawn (in the opening). Positive values are better for white.</li>
-  <li><strong>PV:</strong> Principal Variation, the series of moves the engine thinks is the best.</li>
-  <li><strong>Thick red line:</strong> Marks the best move (in the view of the engine). Multiple chained arrows
-    means that the PV starts with multiple successive moves with the same piece, ie., the engine thinks
-    that the piece will execute a maneuver.</li>
-  <li><strong>Thin red lines:</strong> Other good moves, maximum two. Note that even though these are also
-    quality checked, these are less thoroughly analyzed by the engine,
-    and should be taken with a grain of salt.</li>
-  <li><strong>Thick blue line:</strong> Marks the best <em>response</em> move. Note that this is only rarely shown,
-    since usually, the best response move depends on what the first move is. A typical case is when the current move
-    is forced or nearly so.</li>
