-- Types for script language and version
--

data SimpleScript'

-- | The original simple script language which supports
--
-- * require a signature from a given key (by verification key hash)
-- * n-way and combinator
-- * n-way or combinator
-- * m-of-n combinator
--
-- This version of the language was introduced in the 'ShelleyEra'.

-- | The second version of the simple script language. It has all the features
-- of the original simple script language plus new atomic predicates:
--
-- * require the time be before a given slot number
-- * require the time be after a given slot number
--
-- This version of the language was introduced in the 'AllegraEra'.
--
-- However we opt for a single type level tag 'SimpleScript'' as the second version of
-- of the language introduced in the Allegra era is a superset of the language introduced
-- in the Shelley era.

-- | Place holder type to show what the pattern is to extend to multiple
-- languages, not just multiple versions of a single language.

-- | A script in a particular language.

-- See also 'ScriptInAnyLang' for a script in any of the known languages.
--
-- See also 'ScriptInEra' for a script in a language that is available within

-- Note that some but not all scripts have an external JSON syntax, hence this
-- type has no JSON serialisation instances. The 'SimpleScript' family of
-- languages do have a JSON syntax and thus have 'ToJSON'\/'FromJSON' instances.
