wtf is krig-miner?

Krig miner is a command line program that mines a cryptocurrency called Pearl, abbreviated PRL, using a computer's graphics card instead of its main processor. It is built and distributed by pool.kryptex.com, a mining pool service, and it takes no developer fee, meaning none of the mined coins are automatically redirected to the tool's creators. The program supports both AMD and Nvidia graphics cards, though Nvidia support is described as still in beta while AMD support is more established. The README lists expected mining speeds, called hashrates, for a range of specific AMD and Nvidia GPU models, from high-end data center cards down to older consumer cards, so a user can estimate how much a particular graphics card would earn before setting it up. To use it, you download a prebuilt release for your system, then run the program from the command line with a pool address, your wallet address to receive payouts, and optional settings such as which specific graphics cards to use if you have more than one installed in your machine. It can also expose live statistics in a format compatible with Prometheus, a common monitoring tool, so operators running many machines can track performance over time. There are flags to list detected devices, choose devices by index or by their physical PCI address, include or exclude integrated graphics chips built into some AMD processors, and disable one of the two supported mining backends if only one type of card is present. The README does not describe programming language or source code details, since it primarily documents a downloadable binary tool rather than a library. Support is offered through email and a Telegram channel, and users can also open issues directly on the project's GitHub page.
