How to verify contracts on etherscan

[rstormsf]

Lets say I have the following contact:

pragma solidity ^0.4.11;

import "zeppelin-solidity/contracts/crowdsale/Crowdsale.sol";

contract RomanCrowdsale is Crowdsale {
    function RomanCrowdsale(uint256 _startBlock, uint256 _endBlock, uint256 _rate, address _wallet) Crowdsale(_startBlock, _endBlock, _rate, _wallet) {
    }
}

How would you verify this contract on etherscan?

var RomanCrowdsale = artifacts.require("./RomanCrowdsale.sol");
module.exports = function(deployer, network, accounts) {
  deployer.deploy(RomanCrowdsale, web3.eth.blockNumber+5, web3.eth.blockNumber+1000000000000000, 1, accounts[1]);
};

Manually concatenated contract:

Deployed: https://kovan.etherscan.io/verifyContract?a=0x9b0ec746d4b91742187071ad8d7c06dc7ba3a4c3

Should I copy/paste all inherited contracts that this contract is depended on?

From etherscan:

3. Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files

[interfect]

Contracts built with an unmodified Truffle can't be verified on Etherscan currently; we're waiting for Ehterscan to be updated to support a compiler option that Truffle passes.

See #456 (comment)

Dupe of #456. Closing for housekeeping.
