items that need to be completed with very little effort.
Items can be prioritised and are displayed in a hierarchy, so that one item may
depend on another.

Display (all) tasks.
todo2 [-p <priority>] -a <text>
Create a new task.
todo2 -d <index>
Mark a task as complete.
todo2 [-p <priority>] -e <task> [<text>]
Edit an existing task.`
