cutechess cli and ponder

[elcabesa]

hi everyone,
I'm trying to start a tournament ins cutechess with ponder on, but I'm not able to do it.
Am i doing some mistake? or there is a bug in cutechess searching for "ponder" option instead of "Ponder"?

this is my cutechess command line:
./cutechess-cli -engine conf="Ethereal" -engine conf="Laser" -engine conf="Senpai" -engine conf="Vajolet dev" -recover -repeat -concurrency 1 -openings file=8moves_v3.pgn -each tc=900+10 option.Threads=11 option.Hash=4096 option.ponder -games 2 -rounds 60000 -ratinginterval 1 -debug

this is the std::output of cutechess:

this is the std::error of cutechess:
Warning: Ethereal doesn't have option ponder
Warning: Vajolet dev doesn't have option ponder

Its not an engine option, its just a general flag. Just add either "ponder" or "-ponder" to the end of the command string, and remove the "option.ponder"
