Subject: Why is there so much crafty data in GothicVortex?

Quite frankly, I got sick of hearing about gothic chess, so I downloaded the
vortex program to try it out.

I searched the exefile for the sequence 96, 48, 48, 48, 45, 42, 40, 40 which
happens to be the start of crafty's outside_passed[128] data (at least for
version 19.3).

I found a match in GothicVertex. When I looked further... I found many matches
between the programs.

xlate, tropism, temper, passed pawms, isolated pawns, outside pawns, majority,
piecesquare tables, etc... they all seem to match.

Even the order of data, match the order of the declarations in craty's data.c
file.

Some of the data seem to be modified for a 10x8 board, like isolani, double and
passed pawn values.

I hate to point a finger at someone, but... You are licensing the program for
20$. Did you ask Bob for "the express written permission of the author"?
