This is a minimal but functional ICO. It issues a non-ERC20 standard-compliant token in exchange for Ether. The sale is uncapped, runs indefinitely and tokens are issued at a price of 1 token per Wei.
Warning: Since this token is not compatible to the ERC20 standard (it is missing approve, transferFrom and totalSupply functions and also does not have any events) it will not work with most tools or other smart contracts like token wallets or decentralized exchanges.
