        • Per-task positional args
        • Invoke’s approach
      • Space-delimited flag values that look like flags themselves

    • Other types
• Task execution
  • Base case
  • Pre-tasks

  • Getting hairy: one task, with one pre-task, parameterized
  • Still hairy: one task, with a pre-task that itself has a pre-task
  • All the things: two tasks, each with pre-tasks, both parameterized

  • Task module discovery
  • Additional load options
• Constructing namespaces
  • Starting out
  • Naming your tasks
    • Aliases
  • Nesting collections
