+ -T#          : set level 1 speed objective
+ -B#          : cut input into blocks of size # (default : single block)
+ -i#          : iteration loops
+ -S           : benchmarks a single run (example command: -Sl3w10h12)

+    t# - targetLength
+    S# - strategy
+    L# - level
+ --zstd=      : Single run, parameter selection syntax same as zstdcli
+ --optimize=  : find parameters to maximize compression ratio given parameters
+    Can use all --zstd= commands to constrain the type of solution found in addition to the following constraints
+    cSpeed= - Minimum compression speed
+    dSpeed= - Minimum decompression speed
+    cMem= - compression memory
+    lvl= - Automatically sets compression speed constraint to the speed of that level
+ --optimize=  : same as -O with more verbose syntax 
+ -P#          : generated sample compressibility 
+ -t#          : Caps runtime of operation in seconds (default : 99999 seconds (about 27 hours )) 
+ -v           : Prints Benchmarking output
+ -D           : Next argument dictionary file
