In geth 1.5 the --genesis option has been removed. What do I use instead to add ether to my account?

From Command Line Options - Init:
Init
With the init command it is possible to create a chain with a custom genesis block and chain configuration (currently only the homestead transition block can be configured). It respects the --datadir argument and accepts a JSON file describing the chain configuration.
geth --datadir <some/location/where/to/create/chain> init genesis.json
Example genesis.json file:
{ "config": { "homesteadBlock": 10 }, "nonce": "0", "difficulty": "0x20000", "mixhash": "0x00000000000000000000000000000000000000647572616c65787365646c6578", "coinbase": "0x0000000000000000000000000000000000000000", "timestamp": "0x00", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "extraData": "0x", "gasLimit": "0x2FEFD8", "alloc": {} }
To use the created chain start geth with:
geth --datadir <some/location/where/to/create/chain> console
(I've added console to the end of the last command).
To pre-allocate ethers to accounts, use the format of the alloc
