I already have one here that I still have to review - also must agree with the creator on the exact usage terms.
On the other hand I have the feeling that doing something based on an API will be much more mature and that currently the solution with the .bat file I ship with the miner is not that bad, when deactivating the Windows GUI messages as described by some user a few pages earlier here in this thread. Therefore no news on this yet, since I have to clean up my mind for this.
I also have made script, for my own use, in PowerShell that monitor miner, detects all the problems I had with the miner (0 sol, missing "accepted" shares, miner closing due some error, miner freezes, gpu error, etc...) and act according to the situation (restart miner, start miner, reboot rig, reset cards, overclock cards etc) and log the problems (saves old log files in separate folder, saves reason why script or miner was restarted in separate log file and makes screenshot right before script takes action). Also for nvidia cards I have added monitoring so that relevant info is displayed (power usage, temperatures, fan speeds). I have planned to add some more advanced features, but since there will not be public bounty it's not worth the trouble. Script is fully autonomous, tested it more than week on 2 rigs.
