I would like to add a new role for a user, when he is able to give the right password to Hubot.
Here is the script i have for now :
module.exports = (robot) ->
  robot.respond /PasswOrd (.*)/, (res) ->
    paSS = res.match[1]
    if paSS is "1234"
      role = 'h1'
      user = robot.brain.userForName(res.message.user.name)
      #CODE TO ADD ROLE h1 FOR THIS USER ???
      res.reply "Correct." + user.id
    else
      res.reply "Incorrect password."
It's launching correctly with @bot PasswOrd 1234
But i don't know how to add the role.
Thanks.
