Usage: ${0##*/:-} [OPTION...]

You are able to change a few default behaviours in the getBible API builder
  ------ Passing no command options will fallback on the defaults -------

	Options
	======================================================
   --api=<path>
	set the API target folders full path
		- target folders will be created using this path

	example: ${0##*/:-} --api=/home/$USER/v2

	two folders will be created:
		- /home/$USER/v2
		- /home/$USER/v2_scripture

	defaults:
		- repo/v2
		- repo/v2_scripture

	(these are the target folders)
	======================================================
   --bconf=<path>
	set the path to the Bible config file
		- This file contains the list of Crosswire
		  Bible Modules that will be used to build
		  the JSON API files

	example: ${0##*/:-} --bconf=/home/$USER/getbible.json

	defaults:
		- repo/conf/CrosswireModulesMap.json
	======================================================
   --conf=<path>
	set all the config properties with a file

	example: ${0##*/:-} --conf=/home/$USER/.config/getbible.conf

	defaults:
		- repo/conf/.config
	======================================================
   --pull
	clone and/or pull target folders/repositories

	example: ${0##*/:-} --pull
	======================================================
   --push
	push changes to github (only if there are changes)
		- setup the target folders (see target folders)
		- linked them to github (your own repos)
		- must be able to push (ssh authentication needed)

	REMEMBER THE AGREEMENT (README.md)

	example: ${0##*/:-} --push
	======================================================
   --zip=<path>
	set the ZIP target folder full path for the Crosswire Modules

	example: ${0##*/:-} --zip=/home/$USER/sword_zip

	defaults:
		- repo/sword_zip
	======================================================
   -d
	Do not download all Crosswire Modules (helpful in testing)
	Only use this if you already have modules.

	example: ${0##*/:-} -d
	======================================================
   --hashonly
	To only hash the existing JSON scripture files

	example: ${0##*/:-} --hashonly
	======================================================
   --github
	Trigger github workflow behaviour

	example: ${0##*/:-} --github
	======================================================
   --test
	Run a test with only three Bibles

	example: ${0##*/:-} --test
	======================================================
   --dry
	To show all defaults, and not run the build

	example: ${0##*/:-} --dry
	======================================================
   -q|--quiet
	Quiet mode that prevent whiptail from showing progress

	example: ${0##*/:-} -q
	example: ${0##*/:-} --quiet
	======================================================
   -h|--help
	display this help menu

	example: ${0##*/:-} -h
	example: ${0##*/:-} --help
	======================================================
			${HEADER_TITLE}
	======================================================
