-Build r8lib.jar with both R8 and ProGuard and print a size comparison.
-
-By default, inlining is disabled in both R8 and ProGuard to make
-method-by-method comparison much easier. Pass --inlining to enable inlining.
-
-By default, only shows methods where R8's DEX output is 5 or more instructions
-larger than ProGuard+D8's output. Pass --threshold 0 to display all methods.
