# **security.coffee**
# Module for default site security.
#
# This module is not intented for use, but is here to catch a problem with
# configuration of security. It does not provide any authentication, but will
# allow the server to run read-only.

#### Requires ####
fs = require 'fs'


# Export a function that generates security handler
# when called with options object.
module.exports = exports = (log, loga, argv) ->
  security={}

  #### Private utility methods. ####

  # save the location of the identity file
  idFile = argv.id

  #### Public stuff ####
