Truffle – How to Find the Exact Solidity Compiler Version Used by Truffle?

etherscantruffle

I'm trying to verify a contract I have compiled and deployed onto the network using Etherscan. The contract was compiled using truffle. How do I work out exactly which version of the solidity compiler to select on Etherscan?

I'm running Truffle 3.4.11 and running just: truffle version gives me the Solidity version as well:

truffle version                                                                                                                                                           
Truffle v3.4.11 (core: 3.4.11)
Solidity v0.4.15 (solc-js)

In Truffle version 5.0.0 (currently in Beta) you can specify a Solidity version in the truffle.js config file eg

module.exports = {
  networks: {
    ... etc ...
  },
  compilers: {
     solc: {
       version: <string>  // ex:  "0.4.20". (Default: Truffle's installed solc)
     }
  }
};
