I think you misunderstood something. I think you mean that EWBF miner is only supported.
Because I'm mining kmd/hush/zen with your script.

P.S. Just forgot .... Thank you for it!!!

P.P.S. I think you'd better put something like:
"REM DON"T CHANGE THIS FILE!!! IT WILL BE OVERWRITTEN. CORRECT ONLY IN CONFIG.BAT"
at first line of miner.bat
