Vaporware No More

Vapor Chess is no longer complete vaporware. Today, in honor of the date being 10-10-10 -- although that was mostly by happenstance -- I have finally released the first preliminary version: Vapor v0.01 -- aka 'condensation' -- for both Linux and Windows . And, by another lucky happenstance, the revision number for the Linux build just happens to be 10. I was hoping to keep the same revision number for the Windows build, but alas, mingw does not support the 'error' function, so I had to make some minor changes bumping it to revision 11.
This first version plays legal chess and will consistently beat mediocre players like myself. However, you will likely notice that it is completely unaware of draws by repetition, causing it to draw many games that it should win. I considered adding repetition detection for this first release, but decided it would wait until the next release when I expect to add transposition tables. It seems natural to implement them together, as they both require the ability to recognize when two positions are identical.
