#----------------------------------------------------------------------------------------------------------------------
__usage() {
    cat << EOT

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

  Installation types:
    - stable              Install latest stable release. This is the default
                          install type
    - stable [branch]     Install latest version on a branch. Only supported
                          for packages available at repo.saltstack.com
    - stable [version]    Install a specific version. Only supported for
                          packages available at repo.saltstack.com
    - testing             RHEL-family specific: configure EPEL testing repo
    - git                 Install from the head of the develop branch
    - git [ref]           Install from any git ref (such as a branch, tag, or
                          commit)

  Examples:
    - ${__ScriptName}
    - ${__ScriptName} stable
    - ${__ScriptName} stable 2017.7
    - ${__ScriptName} stable 2017.7.2
    - ${__ScriptName} testing
    - ${__ScriptName} git
    - ${__ScriptName} git 2017.7
    - ${__ScriptName} git v2017.7.2
    - ${__ScriptName} git 06f249901a2e2f1ed310d58ea3921a129f214358

  Options:
    -h  Display this message
    -v  Display script version
    -n  No colours
    -D  Show debug output
    -c  Temporary configuration directory
    -g  Salt Git repository URL. Default: ${_SALTSTACK_REPO_URL}
    -w  Install packages from downstream package repository rather than
        upstream, saltstack package repository. This is currently only
        implemented for SUSE.
    -k  Temporary directory holding the minion keys which will pre-seed
        the master.
    -s  Sleep time used when waiting for daemons to start, restart and when
        checking for the services running. Default: ${__DEFAULT_SLEEP}
    -L  Also install salt-cloud and required python-libcloud package
    -M  Also install salt-master
    -S  Also install salt-syndic
    -N  Do not install salt-minion
    -X  Do not start daemons after installation
    -d  Disables checking if Salt services are enabled to start on system boot.
        You can also do this by touching /tmp/disable_salt_checks on the target
        host. Default: \${BS_FALSE}
    -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.
    -U  If set, fully upgrade the system prior to bootstrapping Salt
    -I  If set, allow insecure connections while downloading any files. For
        example, pass '--no-check-certificate' to 'wget' or '--insecure' to
        'curl'. On Debian and Ubuntu, using this option with -U allows obtaining
        GnuPG archive keys insecurely if distro has changed release signatures.
    -F  Allow copied files to overwrite existing (config, init.d, etc)
    -K  If set, keep the temporary files in the temporary directories specified
        with -c and -k
    -C  Only run the configuration function. Implies -F (forced overwrite).
        To overwrite Master or Syndic configs, -M or -S, respectively, must
        also be specified. Salt installation will be ommitted, but some of the
        dependencies could be installed to write configuration with -j or -J.
    -A  Pass the salt-master DNS name or IP. This will be stored under
        \${BS_SALT_ETC_DIR}/minion.d/99-master-address.conf
    -i  Pass the salt-minion id. This will be stored under
        \${BS_SALT_ETC_DIR}/minion_id
    -p  Extra-package to install while installing Salt dependencies. One package
        per -p flag. You are responsible for providing the proper package name.
    -H  Use the specified HTTP proxy for all download URLs (including https://).
        For example: http://myproxy.example.com:3128
    -b  Assume that dependencies are already installed and software sources are
        set up. If git is selected, git tree is still checked out as dependency
        step.
    -f  Force shallow cloning for git installations.
        This may result in an "n/a" in the version number.
    -l  Disable ssl checks. When passed, switches "https" calls to "http" where
        possible.
    -V  Install Salt into virtualenv
        (only available for Ubuntu based distributions)
    -a  Pip install all Python pkg dependencies for Salt. Requires -V to install
        all pip pkgs into the virtualenv.
        (Only available for Ubuntu based distributions)
    -r  Disable all repository configuration performed by this script. This
        option assumes all necessary repository configuration is already present
        on the system.
    -R  Specify a custom repository URL. Assumes the custom repository URL
        points to a repository that mirrors Salt packages located at
        repo.saltstack.com. The option passed with -R replaces the
        "repo.saltstack.com". If -R is passed, -r is also set. Currently only
        works on CentOS/RHEL and Debian based distributions.
    -J  Replace the Master config file with data passed in as a JSON string. If
        a Master config file is found, a reasonable effort will be made to save
        the file with a ".bak" extension. If used in conjunction with -C or -F,
        no ".bak" file will be created as either of those options will force
        a complete overwrite of the file.
    -j  Replace the Minion config file with data passed in as a JSON string. If
        a Minion config file is found, a reasonable effort will be made to save
        the file with a ".bak" extension. If used in conjunction with -C or -F,
        no ".bak" file will be created as either of those options will force
        a complete overwrite of the file.
    -q  Quiet salt installation from git (setup.py install -q)
    -x  Changes the Python version used to install Salt.
        For CentOS 6 git installations python2.7 is supported.
        Fedora git installation, CentOS 7, Debian 9, Ubuntu 16.04 and 18.04 support python3.
    -y  Installs a different python version on host. Currently this has only been
        tested with CentOS 6 and is considered experimental. This will install the
        ius repo on the box if disable repo is false. This must be used in conjunction
        with -x <pythonversion>.  For example:
            sh bootstrap.sh -P -y -x python2.7 git v2017.7.2
        The above will install python27 and install the git version of salt using the
        python2.7 executable. This only works for git and pip installations.

#
#   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
#       4  install_<distro>_<major_version>_<minor_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
#       4  config_<distro>_<major_version>_<minor_version>_salt
#       5. config_<distro>_<install_type>_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

#       6. preseed_<distro>_master
#       7. preseed_master [THIS ONE IS ALREADY DEFINED AS THE DEFAULT]
#
#   To install salt, which, of course, is required, one of:
#       1. install_<distro>_<major_version>_<install_type>
#       2. install_<distro>_<major_version>_<minor_version>_<install_type>
#       3. install_<distro>_<install_type>
#
#   Optionally, define a post install function, one of:
#       1. install_<distro>_<major_version>_<install_type>_post
#       2. install_<distro>_<major_version>_<minor_version>_<install_type>_post

#       5. install_<distro>_<install_type>_post
#       6. install_<distro>_post
#
#   Optionally, define a start daemons function, one of:
#       1. install_<distro>_<major_version>_<install_type>_restart_daemons
#       2. install_<distro>_<major_version>_<minor_version>_<install_type>_restart_daemons
#       3. install_<distro>_<major_version>_restart_daemons
#       4  install_<distro>_<major_version>_<minor_version>_restart_daemons
#       5. install_<distro>_<install_type>_restart_daemons
#       6. install_<distro>_restart_daemons
#
#       NOTE: The start daemons function should be able to restart any daemons
#             which are running, or start if they're not running.
#
#   Optionally, define a daemons running function, one of:
#       1. daemons_running_<distro>_<major_version>_<install_type>
#       2. daemons_running_<distro>_<major_version>_<minor_version>_<install_type>

#       6. daemons_running_<distro>
#       7. daemons_running  [THIS ONE IS ALREADY DEFINED AS THE DEFAULT]
#
#   Optionally, check enabled Services:
#       1. install_<distro>_<major_version>_<install_type>_check_services
