CLI base for foundry release commands

// Load in our dependencies
var Command = require('commander').Command;
var util = require('util');

function handleActionError(err) {
  // If there was an error, throw it
  if (err) {
    throw err;
  }

  // Otherwise, exit with a 0 exit code
  process.exit(0);
}

// Define our constructor
function FoundryReleaseBase(params) {
  // Inherit from `Command`
  Command.call(this);

  // https://github.com/tj/commander.js/blob/v2.8.1/index.js#L801-L823

    // DEV: This is required for `node@0.10` on Windows (otherwise, it's too slow and we can exit before the flush)
    // DEV: We have a try/catch because this is illegal in `node>=0.12`
    //    Another option is the `exit` package but this is simpler since we are a CLI
