/// setup_bench() builds a list of UCI commands to be run by bench. There
/// are five parameters: TT size in MB, number of search threads that
/// should be used, the limit value spent for each position, a file name
-/// where to look for positions in FEN format, the type of the limit:
-/// depth, perft, nodes and movetime (in millisecs), and evaluation type
-/// mixed (default), classical, NNUE.
+/// where to look for positions in FEN format, and the type of the limit:
+/// depth, perft, nodes and movetime (in milliseconds). Examples:
///
-/// bench -> search default positions up to depth 13
-/// bench 64 1 15 -> search default positions up to depth 15 (TT = 64MB)
-/// bench 64 4 5000 current movetime -> search current position with 4 threads for 5 sec
-/// bench 64 1 100000 default nodes -> search default positions for 100K nodes each
-/// bench 16 1 5 default perft -> run a perft 5 on default positions
+/// bench : search default positions up to depth 13
+/// bench 64 1 15 : search default positions up to depth 15 (TT = 64MB)
+/// bench 64 1 100000 default nodes : search default positions for 100K nodes each
+/// bench 64 4 5000 current movetime : search current position with 4 threads for 5 sec
+/// bench 16 1 5 blah perft : run a perft 5 on positions in file "blah"
