USAGE = '''Usage: tweet [options] message

  This script posts a message to Twitter.

  Options:

    -h --help : print this help
    --username : the twitter username [optional]
    --password : the twitter password [optional]
    --encoding : the character set encoding used in input strings, e.g. "utf-8". [optional]

  Documentation:

  If the --username or --password command line arguments are present they
  will be used to authenticate to Twitter.

  If either of the command line flags are not present, the environment
  variables TWEETUSERNAME and TWEETPASSWORD will then be checked for your
  username or password, respectively.

  If neither the command line flags nor the enviroment variables are
  present, the .tweetrc file, if it exists, can be used to set the
  default username and password.  The file should contain the
  following three lines, replacing *username* with your username, and
  *possword* with your password:

  A skeletal .tweetrc file:

    [Tweet]
    username: *username*
    password: *password*
