#----------------------------------------------------------------------------------------------------------------------
usage() {

  Usage :  ${__ScriptName} [options] <install-type> <install-type-args>

  Installation types:
    - stable (default)
    - daily  (ubuntu specific)
    - git

  Examples:
    $ ${__ScriptName}
    $ ${__ScriptName} stable
    $ ${__ScriptName} daily
    $ ${__ScriptName} git
    $ ${__ScriptName} git develop
    $ ${__ScriptName} git v0.17.0
    $ ${__ScriptName} git 8c3fadf15ec183e5ce8c63739850d543617e4357

  Options:
  -h  Display this message
  -v  Display script version
  -n  No colours.
  -D  Show debug output.
  -c  Temporary configuration directory
  -g  Salt repository URL. (default: git://github.com/saltstack/salt.git)
  -k  Temporary directory holding the minion keys which will pre-seed
      the master.
  -M  Also install salt-master
  -S  Also install salt-syndic
  -N  Do not install salt-minion
  -X  Do not start daemons after installation
  -C  Only run the configuration function. This option automatically
      bypasses any installation.
  -P  Allow pip based installations. On some distributions the required salt
      packages or its dependencies are not available as a package for that
      distribution. Using this flag allows the script to use pip as a last
      resort method. NOTE: This only works for functions which actually
      implement pip based installations.
  -F  Allow copied files to overwrite existing(config, init.d, etc)
  -U  If set, fully upgrade the system prior to bootstrapping salt
  -K  If set, keep the temporary files in the temporary directories specified
      with -c and -k.
  -I  If set, allow insecure connections while downloading any files. For
      example, pass '--no-check-certificate' to 'wget' or '--insecure' to 'curl'
  -A  Pass the salt-master DNS name or IP. This will be stored under
      \${BS_SALT_ETC_DIR}/minion.d/99-master-address.conf
  -L  Install the Apache Libcloud package if possible(required for salt-cloud)
  -p  Extra-package to install while installing salt dependencies. One package
      per -p flag. You're responsible for providing the proper package name.

#   Distribution install functions
#
#   In order to install salt for a distribution you need to define:
#
#   To Install Dependencies, which is required, one of:
#       1. install_<distro>_<major_version>_<install_type>_deps
#       2. install_<distro>_<major_version>_<minor_version>_<install_type>_deps
#       3. install_<distro>_<major_version>_deps

#       5. install_<distro>_<install_type>_deps
#       6. install_<distro>_deps
#
#   Optionally, define a salt configuration function, which will be called if
#   the -c (config-dir) option is passed. One of:
#       1. config_<distro>_<major_version>_<install_type>_salt
#       2. config_<distro>_<major_version>_<minor_version>_<install_type>_salt
#       3. config_<distro>_<major_version>_salt

#       6. config_<distro>_salt
#       7. config_salt [THIS ONE IS ALREADY DEFINED AS THE DEFAULT]
#
#   Optionally, define a salt master pre-seed function, which will be called if
#   the -k (pre-seed master keys) option is passed. One of:
#       1. preseed_<distro>_<major_version>_<install_type>_master
#       2. preseed_<distro>_<major_version>_<minor_version>_<install_type>_master
