Subject: Implement UCI_PlayByNodes option
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=1ed8a494299caa117ca69cbf560fc64eb8dd5098;p=polyglot.git

Implement UCI_PlayByNodes option

Polyglot now suppresses passing any option called UCI_PlayByNodes as
CECP option feature. It remembers the option, and uses its presence
to determine whether to handle a received CECP "nps" command by
using "go nodes" calculated from an improvised TC, or to just pass
it as value for UCI_PlayByNodes. Any "new" command would reset
UCI_PlaByNodes to 0.
