// Solidity Interface:

// Example Solidity use:

// JS Interface:
var abiNameReg = [{"constant":true,"inputs":[{"name":"name","type":"string32"}],"name":"addressOf","outputs":[{"name":"addr","type":"address"}]},{"constant":false,"inputs":[],"name":"kill","outputs":[]},{"constant":true,"inputs":[{"name":"addr","type":"address"}],"name":"nameOf","outputs":[{"name":"name","type":"string32"}]},{"constant":false,"inputs":[{"name":"name","type":"string32"}],"name":"register","outputs":[]},{"constant":false,"inputs":[],"name":"unregister","outputs":[]}];

// Example JS use:
