description: """
  Tactician is a tactic learner and prover for the Coq Proof Assistant.
  The system will help users make tactical proof decisions while they retain
  control over the general proof strategy. To this end, Tactician will learn
  from previously written tactic scripts, and either gives the user suggestions
  about the next tactic to be executed or altogether takes over the burden of
  proof synthesis. Tactician's goal is to provide the user with a seamless,
  interactive, and intuitive experience together with strong, adaptive proof
  automation.
