Help could show available build tools for script command

[andys8]

Creating a new script requires to select a BUILD_TOOL. It would be nice if the available options would be part of the help. Having a look at the source, the options are stack and cabal.

summoner/summoner-cli/src/Summoner/Settings.hs

Lines 60 to 63 in b56aada

	data Tool
	= Cabal
	| Stack
	deriving stock (Show, Eq, Enum, Bounded)

$ summoner script
Missing: BUILD_TOOL

Usage: summoner script BUILD_TOOL [-g|--ghc=GHC_VERSION] [-n|--name=FILE_NAME]
  Create a new Haskell script

$ summoner script --help
Usage: summoner script BUILD_TOOL [-g|--ghc=GHC_VERSION] [-n|--name=FILE_NAME]
  Create a new Haskell script

Available options:
  -h,--help                Show this help text
  -g,--ghc=GHC_VERSION     Version of the compiler to be used for
                           script (default: Ghc883)
  -n,--name=FILE_NAME      Name of the script file

Thanks, this is a nice idea! The easiest way to do this is to rename the metavariable to something like BUILD_TOOL:[cabal|stack]. It can be changed here:
