libghc-propellor-doc 5.3.3-1 (amd64 binary) in ubuntu bionic

 Propellor ensures that the system it's run in satisfies a list of
 properties, taking action as necessary when a property is not yet met.
 .
 It is configured using haskell.
 .
 The easiest way to get started with propellor is to install the binary package
 `propellor' and run `propellor --init'.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
