LOOTCOIN(ł)

A token from the ethereum.org tutorial in the revision that added allowances but not a plain approve. It carries a name, a symbol and a decimals field, a public balanceOf mapping, an allowance mapping and a spentAllowance mapping that records how much of each allowance has already been drawn.

transfer throws rather than returning false when the sender is short and checks the recipient for overflow before adding. An allowance can be granted through approveAndCall alone, which sets the allowance and then calls receiveApproval on the spender, so a spender has to be a contract that implements that callback: an ordinary account cannot be approved at all. There is no owner, no mint and no way to add to the supply after deployment.

This one was deployed as LOOTCOIN, symbol ł, with zero decimal places, so its units are whole and indivisible. Name, symbol and decimals are written in the constructor and no function changes them.
