  Program portion of mcstat
  =========================

  Make sure to add a shebang to the first line to use as a cli program. Note
  the shebang will be visible in webpages, so don't use a shebanged copy in
  a website. An example shebang as follows:

  #!/usr/bin/env php


  Invocation like so:

  $ mcstat uberminecraft.com
  uberminecraft.com v1.7.4 2714/5000 131ms
  Uberminecraft Cloud | 22 Games
  1.7 Play Now!
